Whats the best exhaust sytem out there for my 05 predator? I mainly trail ride, just looking to pick up 5-10 hp. and what do guys use for an air filter? i was thinking of going with twin air?

 

HMF works very well on the Predators.

 

Hey I've got the Bills Pipes header and silencer it sounds good and boost up my preddy really good. look into it heres a link to a web site that offers them really cheap I think its the silencer only though but hey if you dont want to spend money on the header just the slip on your choice but this pipe works good. Or if you wanna get a power package Combo here you go use this link:

my E-series is nice. the tunability feature is really cool. couple that with a head pipe from Rath and i don't know of much better... my $.02

 

I would go with Rath on both the pipe and the filter, and intake system.
