what is the best muffler for power for 4x4 atvs

 

HMF

 

HMF makes great low-end for utilities ive also heard their #1

 

HMF is good, alot of comopanies are starting to make Utility designed exhaust , Pro Circuit make one now, and so does Yoshimura, there is also a Big Gun Utility series, and FMF has them! More and more companies are starting to make some exhausts that are Utility oriented

 

so if I change to a HMF muffler and a K&N air filter I can feel a difference in the power on my 450 kodiak
