I have always wondered. Does removing the baffles in the factory exhaust help out power wise? Like does it do anything else other than sound good? Thanks in advance. Also whats the best bang for the buck for slip on's.

it helps a little helps more exhaust flow also through a k&N on and jjet it... or for a good slip on by a hmf 220$ shipped on ebay

First I don't think it will sound "good" with the baffles removed. Power wise you'll be down and your spark arrestor will be gone.

yeaaa hmf is the best bang for the buck but if you do order one of ebay dont get it from atv galaxy it took 4 weeks to get mine from them...

IMO. removing the baffle from stock exaust just takes the "throat" out of the sound.. a bit more airflow, but unnoticable(power-wise) until you do some jetting..
you could leave the stock exaust as is and try a #155 main jet with a #42 pilot jet.
the stock air-fuel ratio is a bit on the lean side, probably for emmisions.

I have a stock 06 400ex and I took the spark arrestor out and got a EHS cap for a stock exhaust and it sounds a little throatier than stock and the EHS cap comes with a spark arrestor screen.
I also got a UNI filter and EHS airbox lid. And jetted it. To me it has a little more bottom end and better sound. And maybe a bit more power throughout. But really jetting the bike right is the best thing you can do.

ive been through this phase...
It doesn't add power at all, maybe it may feel like it becuase the sound being louder puts it in your head.
The way the stock exhaust uses chambers and crap it doesnt help at all.
It also sounds like complete sh*t!!
Kinda like the exhaust is under water a little.
Its not worth doing or buying

agreed, it makes it louder but it will also sound like shat and people will laugh. everytime i see someone trying to shred and just has the baffle removed and its gargling i just point and laugh

LMAO, i know, right?
Im so glad i found the DMC or else i would be forced to go on a ride without the baffle :( haha.

stock exhaust theres basically no hope for it so aftermarket is the best thing to do.

So I guess you will be pointing and laughing at me while you are spending your hard earned money on a pipe that will only give you very little more power and cost a lot more than what it is worth.
I know I use to have a White Bros. R4 for my 2002 400ex. And actually I think the Stock exhaust with the EHS exhaust cap sounds good and looks good for a lot less money. Why spend a lot of money on a bike that isn't really that fast anyway compared to other bikes. I learned that lesson a long time ago. It's not worth putting a large amount of money into something that isn't going to give you much return in the end. I could see doing a lot to a drag banshee or a 450R but come on guys it's a 400ex for trails why even try to keep up or spend lots of money for nothing. At least I did put a EHS exhaust cap and it does come with a spark arrestor and it's only around $50. After I put the cap on it sounded better than just open. I must admit it's not that greatest but I think it sounds better that stock. And I do feel a power mid power increase I am thinking that is from jetting it, and UNI air filter and EHS airbox lid. Just have fun riding and try not to judge or compete so much it just takes the fun out of it.
11-13-2007, 09:40 PM
whatever floats your boat man its all personal preference. I would much rather have a 400ex than a banshee or 450r. maybe i'm 1 of the few but the 400ex is a great quad for everything. it doesnt have as many problems as other quads yet you can get quite a bit of performance out of it. I love the handling and everything on the 400ex and i wouldnt trade it for anything really. I grew up seeing the 1st 400ex come out and always dreamed that 1 day i would be able to own 1. well i have 1 now and i will always love it. 400ex has great versatility, handling, reliability, and a few mods can really wake up that motor.

11-13-2007, 10:01 PM
I totally agree with you FoxHondaRider and I know from experience and trial and error what the 400ex can do. And I am not trying to bash just putting a few mods on the bike I am just saying that some people like me can go overboard with mods and spend way to much and do to much to there bikes.
And that is why I have another 400ex because I did realize that it's a great bike and is great at handling and is very reliable. But since my bike is just going to be a casual trail play riding bike I want it to stay somewhat quite and ultra reliable.

only thing you can do to the stock exhaust witch there use to already a thread with pics, a guy cut off the end of the pip and puched a 2inch hole right through the walls and another 1 inch hole through the walls. and welded the end back on it musta been LOOUUD!! but that would no doubt add power,,,, but every ones right on removing the baffles you still gotta bypass the walls in the stock exhaust so just buy a HMF slip on er somthin;)

Like Foxhondarider said, its all preference. The power you feel is from the airlid and filter with the jetting. I had the end cap and it didnt do squat and personally it sounded like crap, but thats me. The way the walls are designed, it doesnt do anything by removing the tip. It just makes it louder.
And also, you said pipes give little gain, i completely disagree.
My DMC Alien full system woke the bike up completely, made it rev faster, and gave it a hell of a lot more mid-top end

11-14-2007, 07:38 PM
yeah even a slip on will really wake the quad up. it doesnt give much of a top speed gain but torque and having power through all the gears and RPMs is what it does do.
You go about the same top speed but get there a lot quicker with a pipe and airfilter
SG1
11-14-2007, 08:33 PM
I do agree that a slip on does give you more power. But is it really worth the cost. I had a white bros. R4 slip before on my 02 400ex. It was a good pipe but at or around $200 I just can't really see spending that much money again for a pipe. And believe me I love to spend money on stuff for my bikes. I even have a supertrapp slip on pipe for my kingquad 300 but it does have a good sound to it. I had to put a slip on , on that bike because everything was old and trashed. Anyways i understand what ya'll all are talking about. But the setup I have is good enough for the average rider and it's not LOUD it's just right not to loud and not soft. I didn't really want a loud pipe. All I am saying is that yes a slip on is great but is it worth having people call the police on you or just people being annoyed by a loud bike.

Haha, i got my DMC Alien full system for 45 dollars more than your non-performance tip.
So for 45 dollars more, i gained a few ponies and you gained sound. Im not bashing you if you dont have money for that stuff, but not all pipes are expensive, if you buy used and shop smart you can find some pretty good deals

Sorry I haven't posted back any.
But my main reason for this was because I won't have much money to spend on my bike atleast until tax season. Another ? is how hard is it to rejet a carb? Also thanks for all the advice everyone.
XXXRACER165
11-15-2007, 08:25 AM
Yeah it's pretty easy to re-jet the carb. The whole exhaust thing is personal preference but it is worth the money later on too. You may not gain much power just from a pipe, but you will later on when you do other modds to the engine. Heck, if I had a stock pipe even with the baffels removed on my 440 it would make around 35hp. With my White Bros pro-meg it makes 42+hp. And you also gain performance by saving weight, the stock pipe is real heavy. So all in all, it's worth it. Just my $0.02.

OK, so.
i removed the baffle. does anyone know if theres a hp increase, or if i have to jet it to get more power. I dont know if i should jet it or not
REDRIDDER
08-08-2007, 04:24 PM
buy an exhaust system lol....yes removing the baffle will make the exhaust less restricted but hp gains im not sure i would re jet and remove the air box lid if your going to do it though.
Hondamaster5505
08-08-2007, 04:28 PM
if i remove the airbox lid, i would be ****ed. i dont know where you people ride, but all it takes for me is one ****ing puddle and the the quads screwed until the airbox dries. lol. no offense.

i took the baffle out of mine when i first got it and i found all it did was give it better throttle response. it was defiantly worth it for a bit but i would save up and get a pipe if you want some more hp

08-09-2007, 08:05 PM
took mine off when mine was brand new. sounded so shatty i didn't even ride it with it off i didn't want to embarass myself so i put it back on.
xc_racer1
08-09-2007, 09:42 PM
it doesnt add any hp to the quad. it just makes it louder. the quad will run a lil diff just because its letting more air through. u should rejet it but its not enough that its a must
just get an aftermarket.
theyre well worth it

you removed the baffles or the spark arrestor? if you removed the spark arrestor it just sounds like somebody is farting while sitting in a bathtub with a little bit of water. without the baffles in the silencer it just sounds like a really loud whiny little girl. you will not get any power gains with either. like everybody else said, save your money and get an aftermarket pipe. all you're doing now is making it louder.
honda300EXtreme
08-09-2007, 09:51 PM
yea, i wouldnt do it, they sound horrible without the baffle and the gains arent that noticable...
your flowing a bit more air so i would rejet.
.. you probably only need to bump your main up 1 size..
i would recomend getting a aftermarket pipe and give up on trying to sqeeuze any power out of the stock exhaust...

Thanks for the help guys. i allready removed the baffle though. Good news, im making arrangments with a guy to get a yoshimura slip on. what size jet should i use, im gonna be running a yoshi slip on, and probably a sparks timing key. (if the deal goes through)

that's the funniest sh*t I've ever heard. When I tried to take the spark arrestor out of mine for the first time, I could barely keep it running. It was so out of whack from the increased airflow. It sounded like a sasquatch was sitting on the back of the bike farting. I would second or third that of saving a couple hundred bucks, and buy a slip on. :cool:

id start with a 155 main and a 42 pilot.. then get some color on your plug you might have to bump up the main a size or two but at least you'll be in the ball park

That made me laugh taking the baffle out of anything makes it sound like you have a P.O.S. I have seen so many dirtbikes or should i say turdbikes take the baffle out and you watch them, point, and laugh because it sounds so stupid.

I removed S/A screen (drilled the three spot welds on the retaining ring) and the 'glass pack' from inside the back plate of my stock muffler with a dremel, put the S/A screen back on with stainless sheet metal screws and it sounds pretty good.
.. I just wanted to be able to hear the engine above the wind noise in my helmet, so I could hear when to shift, lol.
Now it has a 1.5" outlet instead of that weenie 3/4" muffled outlet.
Probably not any significant power gain, but that wasn't my goal, anyway. My other 400 has the power. At least this one sounds better now.

BTW, I've seen new 'end caps' on eBay, that do essentially the same thing I did, without the spark arrestor... Anybody try one of them yet? They're a little pricey for what they are.. something like $40.

cut the stock pipe in half with a sawzall and it'll sound better than taking the baffle out. (go buy an exhaust) I really don't know why i waited for the exhaust on mine.

those "performnce end cps" on ebay for 40 bucks are a joke. Thats what i did, i cut out the end in the tip.

We will not describe the understandable nature of deposits in the muffler, fumes, soot, rust, as a result, exfoliating from the walls of the muffler, block or create difficulty in the exhaust.
To correct the current situation with the muffler, it is proposed to clean it. To do this, you can use several practical methods. It should be noted that the proposed methods differ in the level of complexity, as well as the level of efficiency achieved in cleaning. Heavily clogged mufflers require serious intervention, up to cutting the body, but first things first.
We clean the muffler with a cable.
The use of a wire rope is one of the most common methods that is easy to clean mufflers with light to medium carbon deposits. One of the ends of the metal cable should be clamped into the drill chuck. The second end of the cable should be dissolved, making something like a ruff. It is necessary to consistently move into the muffler pipe with a cable. In this case, the pipe should not be removed from the ATV. The rope must be turned slowly. Cleaning should be done until the rope stop is reached.
Chemical muffler cleaning.
The second method requires the use of such a tool as "Mr. Muscle". You can buy such a powder at any store; it is intended for cleaning clogged sewer pipes. The muffler must be removed for cleaning in this way. Then everything is simple: pour the powder diluted in hot water into the muffler, after closing one of the holes with a wooden gag and shake it well. We repeat the procedure several times. There are also special chemicals for muffler cleaning, for example: LIQUI MOLY DPF Cleaner.
The expediency of choosing this method is noted when there is a small amount of deposits in the muffler.
Cleaning the muffler with a gas burner.
You can also use a gas torch or a blowtorch, the method is suitable for fairly heavy muffler clogging. We warm up the muffler well from all sides over an open fire (some use a fire), then tap the pipe stacks with a wooden mallet or stick so that the soot exfoliates. Then we thoroughly blow the muffler with a compressor. After this cleaning method, the muffler will have to be painted with refractory paint (commercially available).
Cutting muffler for cleaning.
Cutting is the method to be selected if none of the above methods solved the problem. Part of the muffler can is cut off with a grinder, and you get full access to all the internal parts of the muffler. And then it’s a matter of technology, after mechanical cleaning, we shake out the soot, weld the cut off part of the can back, clean the muffler to a shine, degrease and paint it with refractory paint.
"How to op...
Wilderness tuning..."
How often do you have to deal with bad weather on the road? Given the peculiarities of the domestic climate, probably quite often. If this is the case, you are of course using deflectors, which not only help protect your side windows from small stones and dirt, but also allow you to open them slightly in the rain, eliminating the possibility of moisture getting into the car, even with a strong side wind.
Contents
The fulfillment of such a task is carried out by creating with their help a certain aerodynamics of the car body, which does not allow dust flows to get inside the car. Such a "cut-off" is always installed in the upper part of the side window, thus creating a semblance of a visor, due to the shape of which, dirt and dust do not enter the passenger compartment not only from the front, but also from the side. Well, in addition, it provides uniform ventilation of the cabin even during high-speed driving, which is usually accompanied by strong air currents entering the cabin.
Depending on the cost of products, there are 2 ways of fastening them: based on double-sided tape (cheaper) or plug-in (more expensive). The method of fastening also affects the safety of the car's paintwork - cheaper products quite often spoil it.
Before removing the side window deflectors, you need to prepare the necessary materials for this.
As we have already said, the methods for dismantling the cutter will vary significantly, depending on the method of its attachment. However, first things first.
So, if your deflector is attached to the door with double-sided tape, to remove it you will need:
If, on the other hand, plug-in deflectors are fixed to your car, you will have much less problems when removing them, and you will lose much less time than when removing invoices. For them, all you need is:
So, after determining the method of fastening and preparing the necessary tools, we proceed to dismantling.
If the deflectors are attached to the door frame with adhesive tape, then in order to remove them safely, the following algorithm of actions should be followed very clearly:
