Hey fellas I ride a 2001 warrior and i've herd only good out of the HMF sport series pipes but i am sitting on a deal on a white bros mx4 series pipe I was wondering if anyone has any comments on the MX4 i need to know soon be4 it's gone.... so let me know fellas

 

i say go with the hmf....ive seen allot of things with the white bros that i dont like..poor quality and not the best power.

 

lol go look at all the dyno chart and the white brother is one of the best. Like always top 3 so i wouldn't say hmf is better.
I use to have a wb on my predator and it was very good.
just my 0,02$ ,joel

 

i have a white bros e series and i love it on my warrior.

 

None of ya have ever used or herd this pipe though? the mx4 series i can get it for like 200 to my door
