I was wondering,does the slip on HMF exhaust add any HP and is it loud?

 

You don't gain alot of peak hp but you do gain alot in the midrange. Here's the HMF on mine.

HMF

 

im getting an HMF too. It helps GREATLY with bottom and mid range.. and barely any at top. I was wondring if it is loud..

 

Just put one on my warrior it sounds good has a pretty deep tone, and doesnt appear to be super loud but going riding today with it for first time so havent opened it up yet. I think HMF states it adds 2hp across the board for whatever thats worth hehe. For $200 think its very good choice for warrior/raptor 350 they look good as well.

 

almost any aftermarket exhaust silencer will add a little hp and definitaley make it louder. But if you are looking for (in my opinion) twice the power, go with a full exhaust system. HMF is a very compay but i prefer White Brothers or FMF.

 

Got the HMF slip on, and my son has the full HMF exhaust on his 660, and mine is as loud as his. When I got mine they were'nt showing full exhaust for 350...I wish I would have waited a while longer....but I like it.

 

Still no full system from HMF, they won't make the headpipe because they can't make any power with a replacement and they will only sell something that makes power.

 

Guess I should have made my post a little clearer, as far as full exhaust system, when I bought my HMF slip on, catalogs, etc. were'nt showing any full exhaust systems, did'nt necessarily want a HMF, son bought his, saved on shipping and a little price break buying 2 pipes, plus I wanted the red.
