Who would be interested in a quieter pipe?

How much power would you be willing to give up? If you were going to lose, where would you want it – Bottom end, middle, top? What would you be willing to spend?
I’m sure we could get some assistance from the AMA or Blue Ribbon Society. I’ll make some calls and inquire.

I would give up 2 hp and be willing to add 2lbs in weight (compared to an aftermarket unit). This might be enough to get from 104db to about 98db-100db or maybe even less if we are lucky.
The item that I would stress is a durable and well made exhaust. Maybe all stainless and a little thicker guage than some of the aftermarket pipes. A thicker guage will help keep the noise down.

I'm man enough to admit that I can't use the full potential of my bike with the stock silencer & Thumper insert - make it quieter & lighter than that with a rubber mount like the YZ & I'll be content.

DB = Same as stock pipe or less
HP = Increase of 3HP over stock bottom to top
LB = 1 lb less than stock
$$ = $300 for rear half of pipe

I am glad you finally came to that conclusion !
When I saw you straining to handle the BRUTE TORQUE of your Wife's Honda XR250...I knew something was amiss!
Bri, c'mon, NEVER publicly admit anything like that. It would be like me mentioning the embarassing surgery I had that Mike in S.V. keeps bringing up!
No pun intended!

I entered my first M/C race on Sunday - a HS at the club. I rode the C class - all us were lumped together, under 35, 35-40, 40+. And the mini's ran in the 'C' race - a mini is anybody under 18, bike size doesn't matter. There were kids on YZ250Fs, CR250s, YZ80s etc. Let's just say I was shown how truly slow I am by a kid on a YZ80. Granted I was riding the XR but I don't think it would have much difference if I was on my WR or my KX500. Those damn kids have no idea of fear or pain & suffering. The only place I was truly at a disadvantage that can't be blamed on rider ability was the steep uphills that the XR just can't pull with me on it.
As far as your surgery goes - we have the technology. It's too bad you don't work for the city of San Francisco - the board of supervisors just voted to cover sex change surgery for city employees
Hey man, don't knock the mighty XR250 - it's the only bike to have when in pure survival mode.

Because I'm lazy and an aftermarket manufacturer should be able to build a pipe that bolts onto my WR AND offers the same performance as the stock KTM silencer for less money than I could do it myself. Hell, Yamaha should be doing this from the factory.

I demonstrated the bike to a friend who owns one too and he noted how much quieter the bike sounded. He insulted me with the "wuss" comment and said it souned like a lawn mower. Tough beans, I like it and it gives me the ability to make the bike quiet by backing off the gas.
If you are willing to spend the coin, then this is it. There is definate decrease in noise, however don't expect a bike Grandma would love. Besides, these are performnce bikes. You don't want to be called a wuss and have it be true.
Go for the pipe, you will like it.

The whole point of this post is to see if we can flex our collective muscle to get the manufactures to come up with something. I believe they can. Hope you will join us in this effort. Thanks, Paul M.
Thanks Paul - That's it exactly!

The bike magazines are part of the problem! They say they don't approve of loud bikes and yet every WR test is run with the throttle stop cut, intake baffle removed, and the plug out of the exhaust.
"Sure we complained to Yamaha about the excessive noise, but since they keep taking us riding in frigging Costa Rica it's hard to bitch too much. Besides we wouldn't want to be taken off of the invite list next year! They are one of our best ad accounts"
Sorry, just by 2 cents.......
I do feel better though......

Some of you guys want it all but you would have better luck winning the lotto.Believe that Yamaha as the resources to quiet these bikes with out performance loss.The compromise is big huge mufflers and allot more wieght.If your primarily trail and play riding you probably don't want to sacrifice to much bottom end.A certain amount of exhaust back pressure helps reserve bottom end power.Most of the time back pressure increase go's hand in hand with noise reduction.If your looking for good performance and very liveable noise e-mail email@example.com

Many people on this site have made our own inserts. Mine works great. The thing most of us are looking for is a LIGHTER system that is quiet that doesn't choke up the bike. Your insert doesn't make the stock pipe lighter. Thats one of the big issues. Why don't you post a pic of this insert you have made?
