when you pipe and remove lid and rejet a raptor?

lets say a 300ft race....how many lengths should the pipe/mods beat the stocker?

 

supposively pipes add anywhere from 5-10 hp on raptors so ur gonna be holding on a lot harder lets just put it that way...

 

Yeah, you will notice a huge difference over stock, i just recently got the Dmc Alien full exhaust kit for my raptor, jetted, k&n air filter, power lid, and make sure you hold on tight for that first ride with the new stuff, it will suprize you if your not ready for it, when it was stock i had to somewhat try to get the front end up when i was up at the dunes, now i just hammer it in 2nd and it stands up, gotta love the power.
