Re: exhaust

The Polaris rep in our area (the guy who is paid to let salesmen thrash his rzr) has the factory fmf/polaris setup on his.  It's a little louder, sorry but i can't remember his horsepower claims.

I'd spend the money on suspension!

Re: exhaust

Re: exhaust

Rocky Mountian catalog came today.  Big Guns makes one with a baffle/spark arrestor you can take out.  Check rockymountain.com  for more info on pricing etc.

Re: exhaust

Aftermarket pipe makers makes lots of claims of HP gains on 4 strokes, but don't swallow it. They might work in some 2 stroke cases where the manufacturer didn't know what they were doing, but unless a stock 4 stroke pipe is severly restricted, all you'll gain is annoying noise and a loss of vehicle value.

Are you really trying to say all after market pipes for all 4 strokes don't work any better than stock?  I am sure you weren't able to type that with a straight face.

Re: exhaust

I'm saying the 4 stokes aren't tuned with the pipe, just 2 strokes. On 2 strokes the pipe is actually part of the combustion chamber in a sense. On a 4 stroke it's just an exit channel for the exhaust. Some think they have more power because it's louder. I remember thinking that same thing when I was 12 and took the muffler off my Honda 90.
