How to silence atv exhaust


How To Make An ATV Run Quieter, Silent ATV Exhaust – AtvHelper

Making your ATV run quieter is actually not all that hard to do. It all starts with the exhaust noise. There’s a few ways you can lower the exhaust noise of your quad that are pretty easy to do yourself.

Suppressing the sound your ATV makes is pretty popular among hunters, bird watchers, or anyone that wants to disturb the wildlife where they ride as little as possible. Others want a quieter machine to avoid bothering the neighbors or to comply with sound pollution regulations in their area. Whatever the case may be you have a few options available to quiet down the noise your ATV makes.

The most effective way to reduce the sound an ATV makes is to install an aftermarket ATV exhaust silencer on your machine. Other options include packing the muffler with sound dampening materials, installing a spark arrestor, or repairing any leaks in the exhaust or muffler system.

ATV Exhaust Silencer

This is the preferred method, and you’ll see why later on when I talk about the other options out there. Getting and installing an aftermarket ATV exhaust silencer is so simple and straight forward, and suppresses the exhaust noise better than anything else you could do.

There are plenty of ATV exhaust silencer kits out there to look through. I suggest you start with this Silent Rider ATV Silencer on Amazon. It’s a bit more pricey than some of the other options out there, but well worth it. The Silent Rider makes many versions of this ATV silencer so you should be able to find one that fits your quad. They make it a custom fit for your machine and even offer a one year warranty.

If you’re a bit strapped for cash you could try this Universal Fit Kolpin Stealth Exhaust 2.0 with Heat Shield. Sure it’s about half the price of the Silent Rider, but it’s also about half the star ratings too.

Don’t be put off by that though, most of the complaints are about fitting issues. If you’ll be able to weld this on, you shouldn’t have a problem. The makers of this ATV exhaust silencer, Kolpin, claim there will be no loss in performance with this silencer. That’s a plus in my book.

Pack The Muffler

If you’re trying to spend as little money as possible, you’re looking at the do it yourself approach. You could silence the existing exhaust by packing the muffler with sound dampening materials.

I don’t recommend doing this because you will be restricting airflow out of your engine and could cause overheating or other issues. Still, It’s a viable option if you need to quite the engine quickly and cheaply.

I would advise against using steel wool or anything of that sort because it will heat up pretty quickly in your muffler. Eventually blowing red hot pieces of steel all over the trail. Instead try using heat resistant insulation of some kind.

Sure, you could go into your attic and grab some fiberglass insulation to stuff in your muffler. That should work fine, but the best thing to use would be this Standard Muffler Packing Material, or something similar.

Install A Spark Arrestor

This is low down on the list because it’s not made to reduce the sound of your ATV exhaust. It’s intended to prevent hot debris from being blown out of your exhaust and catching the woods on fire. But, it does reduce the sound your engine makes a little bit.

If you’re going to use the ‘pack the muffler’ method, I highly recommend you make sure your ATV has a spark arrestor because the chances of high heat material getting shot out your exhaust is a lot higher.

It’s pretty easy to install a spark arrestor, and you can find them for around 20 bucks online. Here’s an HMF Spark Arrestor For Exhaust from Amazon to get your search started. As for the install, you simply take the end piece off your exhaust tip, put this on the end of the exhaust and reinstall the end piece.

Repair Exhaust And Muffler System

This may seem like a no brainer but a lot of people don’t realize their exhaust system may have a crack or rusted out areas. If you’re trying to quiet your ATV because you feel the exhaust is overly loud, it may be as simple as fixing the existing exhaust system on the machine.

Check over the exhaust and muffler systems for any small cracks or rusted out areas. Get a flashlight and take care to get a good look, even a small hairline fracture could be causing extra noise.

Repack Exhaust Silencer

This is another simple maintenance tip I’ve noticed not many people know about. If you already have an exhaust silencer installed on your quad, you may just need to repack the insulation.

Some ATVs come stock with a silencer on the exhaust from the factory that you will need to repack. You can use the same silencer packing material I recommended up above in the ‘pack the muffler’ section.

You should only need to do this every few years depending on how much you ride. It’s a simple process. Start by taking the exhaust silencer off the exhaust and disassemble until you have access to the material in the silencer.

Pull out all the old silencer packing material and clean the core. It doesn’t hurt to blow out the silencer with compressed air if you can. Install new packing material and reassembly the silencer. Easy as that, you’re done.

Sum It Up

There you have it, there’s a few different ways to make your ATV exhaust quieter. I would start with inspecting your exhaust and muffler for damage, rust, and cracks to make sure you don’t have a problem before going through the process of suppressing your ATV exhaust.

If everything looks good, I would repack the stock silencer if you have one, or go ahead and buy an aftermarket silencer for best results. Install a spark arrestor for a little help with the noise if you don’t already have one.

In a pinch you could always pack the muffler, but remember, that could lower your airflow which will reduce your engine power or cause problems.

How to Quiet ATV Exhaust Noise

Are you a hunter, avid rider, person who wants to have a chat with a passenger whilst riding or simply hate the loudness of a stock exhaust?

Then this article is for you as i discuss 6 ways on how to quiet that exhaust, also with additional tips.

Silencer

Image by Anya1986 via Flickr

The best, although somewhat expensive way to make your ATV more quiet is with a silencer. Aftermarket silencing mufflers are mounted onto the stock mufflers which help reduce the exhaust noise.

How much will one help? Well, it entirely depends on make and model of your quad, but expect to see at least a minor decrease in the loudness.

There are many of them you can choose on the market, but in my opinion this one made by Kolpin on Amazon (link) is the best.

The amazing thing about it is that it’s also universal, and will work on most ATVs out there.

Repacking it

If you already have a silencer on your quad or are willing to get one make sure to not forget repack it. Some people repack them once a year, others every two weeks but i would suggest to do so just when you start to notice that it sounds louder than usual.

The main item of this DIY project is the packing material which you can also get on Amazon.

Here’s a tutorial on how to get it done.

New muffler

Another thing you could do is replace the stock muffler completely with a new or used one. Mufflers, just like the engine parts, start to perform worse over time, so it makes sense to replace them for the better good – it’s also a great cheaper (especially if you get a used one) alternative to a silencer.

In fact you might consider replacing stock muffler even if you will get a silencer anyway as that can make the four-wheeler even less loud. You could also replace the muffler that comes with the ATV with an aftermarket one, especially with a longer tail pipe.

Additional ways

Things like chrome exhaust extension tips, flexible metal conduits, high temp flexible hoses, vacuum hoses or even bicycle inner tubes can be attached to the end of a muffler to reduce the noise a bit (just make sure they can go into or over the exhaust ending). Longer extensions will make the exhaust noise more quiet – there are even people who get a couple of feet and wrap it around the bike!

Car mufflers have been used as homemade silencers on many engines for ages, so welding one onto an ATV can be a smart idea, although it might not look as pretty.

Make sure that the exhaust itself doesn’t have any cracks as they might leak additional noises – clean the spark arrestor too as it can also contribute to it.

The exhaust is not the only thing adding noise

Sure this article is about exhaust noise reduction, but i’m pretty sure you will be interested to know that the overall ATV noise production comes not just from it.

Simple things like making sure any accessories you have on your ATV are tight and not dangling around can drop off a decibel – also, go around and tighten any bolts that might seem loose.

Different ATV’s make different noises, as some might make a louder noise from the transmission than the muffler itself, so in that case there might be nothing much to be done.

Should you do it?

Image via Pxhere

Many folks might think that adding a silencer or any sort of modification to the exhaust system will make the ATV slower but that’s not always the case. Sure there are mufflers, silencers or things you could do that will decrease the 4 wheelers speed or pulling power, but even then i would rather lose a little power and make the thing more quiet.

Usually newer quads are not as loud as the older ones, so if you want to get the best results possible, you might just start saving money.

A tip for extra stealthiness

If the quad you have is a manual, it would be a no-brainer to not crank the throttle constantly, but get on the highest gear and drive slower which should reduce the sound pretty drastically.

Respecting the others

The reason why many ATV riding places get closed down or new ones don’t open is because the riders don’t respect other’s demands.

Even if it’s not illegal sound polluting the outdoors can ruin the experience of many others. For a lot of people being outside means connecting with nature, so going out and ripping it up on the quad doesn’t really make much sense, and often times those are the people that report the noise disturbance.

Many tracks, even competition ones have a minimum sound level which is often times at least 94 decibels – stock quads can produce over 102. Number wise that might seem not a big of difference, but every three decibels the the sound pressure nearly doubles, so 102 db is four times louder than 94 db.

I hope that puts it to perspective on just how important it can be to have a wheeler more quiet.

How to make a quiet exhaust. How to reduce the sound and volume of the exhaust

08/27/2018

What can I do to make the car run as quietly as possible? The main cause of loud noises on the road is the exhaust system. Make changes to it, and you will feel how much more comfortable it is to be in the cabin. We tell you how to make a quiet exhaust on your own, without resorting to the help of specialists.

Why Exhaust System Makes Loud Sounds

To understand the cause of loud noises, you need to know how a standard exhaust system works and what stresses it is subjected to during operation. Temperature changes (cold and heat), contact with moisture, dirt and dust - all this provokes the development of corrosion. After some time, the sections of pipes with perforation and those parts of the partitions that are located inside the muffler can burn out. Sound reflectors gradually become unusable. In particularly difficult cases, only one thing will save you from a loudly working exhaust system - replacing the old muffler with a new one.

Where do loud noises come from in the exhaust system? They have different origins. Firstly, these are sounds from the expansion of gases that pass through it. Secondly, it is the noise caused by the vibration of the components of the exhaust structure.

How to make the muffler sound quieter

You can do all the work listed below by yourself. So, how to make the exhaust quieter:

  • install an additional resonator;
  • replace the old resonator with a new one;
  • replace the muffler with a new one.

If everything is clear with the third method, then the first two need additional clarification. Let's start with what a resonator is and what it is responsible for.

What does a resonator do

An exhaust resonator dampens (disperses) the sound vibrations that result from loud exhaust gases escaping from the combustion chamber. Structurally, the resonator is a multicomponent device through which gas flows pass. In everyday life, it is often called the "middle muffler", since it is located precisely in the middle part of the exhaust system. Gases under pressure enter the resonator, lose some of their energy and move on with less momentum. Later, passing through the system of labyrinths in the silencer, they dissipate even more.

The loudness of the sound is influenced by several parameters of the resonator at once: its size, shape and design. If the operation of this device is disrupted, the entire exhaust system suffers, and first of all the driver: he not only listens to loud sounds, but also breathes gases that penetrate into the car interior. At the same time, the engine suffers - its service life decreases.

The performance of the resonator depends on three factors: the condition of the catalyst, which reduces the concentration of harmful substances in the exhaust gases, the diameter of the pipes and the cleanliness of the muffler itself. If the device works stably, it means that the gas passes freely through its cavities, but at the exit its energy is several times less than at the entrance. For foreign cars, exhaust system components are usually made of denser and heavier materials, which are less prone to vibrations. This must also be taken into account when evaluating its work and, most importantly, the “loudness” while the car is moving.

How to install a resonator

Above we wrote about how to reduce the exhaust sound - install an additional or replace the old resonator with a new one. Here's what to do in the first case:

  • cut out a piece of pipe that connects the main resonator and muffler;
  • install and weld an additional resonator to the vacant space;
  • check the correct operation of the ignition and fuel supply system.

As an alternative to the standard resonator, you can choose a model with sound-absorbing filling. In such a device, the internal cavities are filled with basalt fiber or a material with similar characteristics. In addition to the main property - the ability to absorb sounds - the filler is durable and tolerates heat well. The only drawback of such a device is the high price.

You can learn about your car's exhaust system in depth, learn tips on how to reduce the volume of the exhaust on the Internet forums and even put them into practice - do it yourself. However, it is better to entrust the solution of the problem to the specialists of the “Muffler Master” service.

You can make an appointment for diagnostics in St. Petersburg by calling the number listed on the website. The service by appointment is open from 10:00 to 23:00 (for other clients - until 19:00). If you need advice on choosing a new exhaust system component, our experts will help you with this and organize the supply of necessary spare parts. We know how to make your car move quietly and with maximum comfort for passengers!

Yes, it differs in its throughput by the number of labyrinths, the diameter of the mesh, the thickness of the metal "Okovskaya" can, according to its technical characteristics, will rather not suppress, but increase the exhaust roar. who does not believe can check.

How much will it cost at Can Am?

monssson

Only on x8. Other quadras require the presence of vehicles. But if you have a desire, you can send it to the "bank", but how to fix it and the adapter will have to be thought for yourself, this will be considered not a finished product, the price of a ruble is two cheaper, the price was announced above!

Amigo 28

Does the tow bar continue to perform its functions after installing the silencer or is it removed every time?

monssson

the towbar remains in place, unless of course it is removable and performs its functions in any case. on the other hand, the muffler can be removed quickly and easily and can be removed!

RESPECT TO YOU.

aak

how much does your muffler "strangle" the engine?

monssson

the diameter of all holes is in no case less than the standard exhaust muffler. Prima, the gas flow is divided into many small ones, its passage through the muffler is lengthened due to the many labyrinths at the end, it unites and freely exits closer to the ground, which also underestimates the noise level.

monssson

The dynamic performance of the motor is not affected. in any case, whoever puts it is not in a hurry unnecessarily, but quietly, without noisy, drives up to the right place and also quietly leaves in that sense of this device.

Vitalya imashev

Cool thing I met a hunter in the forest on an ATV with your additional muffler I really liked the result of the exhaust in general it’s not audible like the wind in the forest I at first thought the scooter was driving through the forest. now it caught fire the desire to also ride and enjoy the singing of birds in the forest and not scare all the animals for five kilometers, and the neighbors will grumble less, tell me what you can offer me for my BRP 1000, I know that it’s not according to your model, I will be very grateful for any advice and help.

difficult situation with the muffler from the taiga snowmobile. I have never come across looked pictures thought how to help and came to the conclusion that the engine compartment does not give vent to fantasy. can't be added! and the native is competently made to modify it is not worth it. either the engine will choke or everything will light up. Yuriysergievposad try to wrap the entire exhaust system with non-combustible material like tape as in the picture. % 15 will be quieter.

Good afternoon, are you doing Haysan 500? And another question, is there any power loss after installing your muffler?

monssson

You can make it for any ATV and bugs, including Haysan 500 stealth, but if you have it in the garage !!! currently stands sf moto x8 and sf moto 500 On the issue of power loss after installing an additional muffler, I will answer - it’s a bad case! The basic rule in the manufacture of a muffler is that the labyrinth and all holes with their number should not be narrower than the outlet of the standard exhaust system!

Chinese Lifans did yes but only the silencer itself!!! you have to connect and install in place on your own, the models are different, the layout and location of the power unit are also different for everyone. I always advise such Kulibins to take the exhaust gases further from the seat so that the combustion products are not inhaled !!! There were no complaints.

monssson

BMP193 Well done, I just forgot to mention that it is three times larger than the regular one and you can’t put it without welding! drum! watch the comparison video.

monssson

ATV friends!!! Work on the creation of a universal muffler has ended. The barrel itself has remained unchanged, since for eight years it has proven itself from the best side and does not need to be improved. Innovations are a strong bracket with double fastening to the barrel and the possibility of bending in the right direction! and the introduction of AISI 304 stainless steel flexible bellows for exhaust systems. The only thing I ask when ordering is the outer diameter of the standard muffler outlet and discuss the installation location, since not everyone has a tow ball mount !!!



monssson

Despite the fact that the labor intensity and the cost of manufacturing a universal additional silencer is an order of magnitude higher than usual, we will not raise the price this year.
