How many hours should the Raptor have on it before installing a new header and pipe? Have you guys installed a new exhaust system from day one?

 

I rode my 02' raptor for about 10 hours and then I put on the White Bros. "e" series. Everything runs great. I'm not sure if it really matters if you put a pipe on when you first buy it or wait until the break-in period is over. I wouldn't think it would make much of a difference. After all, companies like alba sell them out-the-door with a pipe already on it.
