Best exhaust around.
I recently upgraded from a sport series HMF to this exhaust and I am very pleased. I have run some of the other as they say "big power exhausts" and I can tell you this exhaust has out pulled them in the torque department for sure. I like knowing I have the ability for this exhaust to be modified to fit so many situations.

Awesome exhaust!!
I bought this exhaust for my Honda 400ex and what a difference!! It open the quad up so well!! The only thing I didn't like was that hmf didn't send any jetting specs. So all I did to mine was put a sparks advanced timing key in which gives the engine way more throttle response. I also did a choke delete. So all said and I put a 42 pilot yet in I lowered the Clip one and put a 175 main jet in it. And a word of advice don't waste your money on a dyno jet kit. Just go to your local atv dealer and get your jets there. Over this is a great product sounds amazing!

I have a '05 trx450r and was wanting to buy one of these pipes....does it come with a jet or do you have to purchase that sepretely?
Over 3 years ago Location: iowa
you will have to purchase the jet seperatly. dyno jet makes a great jet kit. you can also go to hmf's web site and order the pipe with the jet kit needed as a kit

if you go with slipon you should be fine but if you get a full system you should buy the hmf optimizer which cost 200 dollars
Over 3 years ago Location: iowa
If you go with a full system recommend going with the hmf programmer. However if you go with just the slip on there should be no other mods needed
