What type of power do they give?

[bloodmoney23]

a lot more than stock. its basically one of the top exhausts used on 450r's. good pipe to go with but i cant give you exact hp/tq it adds.

http://www.wppracing.com/ has some Rossier dyno graphs along with a bunch of other exhausts to compare it to.

Heres a real world experience.........dyno's dont mean as much to me as a butt-o-meter!!! I had a DMC Alien exhaust on my 07 450er first, and it was a little better than stock. I switched to the Rossier system and the difference was amazing. It was almost as dramatic as when I added a stg. 2 hotcam to my 400ex. I know dyno's are actual proven power, but sometimes hearing someones personal experince with a product helps more. IMO !!

I second this.... i had a Big Gun full exhaust on my 04 when i bought it... for one it sounded terrible, for two it looked terrible.... and three it didn't seem to have the grunt i expected.... i put a Rossier pipe on it and was impressed as soon as i started the bike!!!! Also it costs alot less than most of those magazine pipes....

P.S. You won't find better service either....

rossier is as good as you can get

there are a couple others that are "as good" but none that are better

I went from the hrc exhaust to the rossier, the biggest diff was the throttle response "instant"

next was the exhaust tone, a little on the loud side but sounds great

it may have a touch more on top end but not alot
