I am looking for mods for my Warrior and I am told that the first thing to change would be the pipe. Can anyone tell me which pipe gives the best performance boost for my quad?

Thanks

 

there is really no best but everyone has a favorit. i have a white bros and love it. its really loud. the tested several pipes on a 400Ex in dirt wheeles and wb won. CT racing pipe is 2nd best cus its even louder same hp and exceleration. I have been really happy w/ mine

 

I got a LRD on mine ilike it alot. I mite the white bros. in the near future though> My pipi is loud also.
