Has anyone ever heard of Rossier Engineering. There atv exhaust looks like it is well put together. They have a Dyno sheet that shows it making 45.5 rwhp a gain of 7.5 over stock with jetting. Just curious if anyone has heard of them. Text

 

yoshi comp series makes 46.6hp and the CT makes 48, anythign north of 45 is good..

 

Then they are pretty generous with stock benchmarks because most stock bikes make right around 35 hp. That would give you about 42-43 hp with that pipe. Most Raptor pipes will give you an 8 hp boost, the best claim 12+.

 

No raptor pipe makes 12hp on a stock engine period. Some body using the dyno is producing #'s they want to see. Look for a pipe that has equal length primary tubes and a burns style collector. The only pipe out there meeting those requirements is a Rossier.

 

Hmm, I smell troll.
