Great pipe Easy to tune

Changed stock jet to #92 and shimmed the needle valve 1/16. Great power gain. Low end pulls much harder thru 2nd gear. TRX250X

Simply the best!!!

I have this HMF full system on my PowerMaxx equipped Big Bore 558 Predator. It is AWESOME! Great power and killer sound! The R&D they do on each exhaust is incredible! I highly recommend it!

Power!

I put this on my TRX250X along with a moose jet kit and an UNI filter and wow, I thought this quad struggled with low end but I love it now! Easy to install, looks good, and power is immense. Definitely would buy again

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!

A: Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

Q: Full system exhaust?
2 years 2 months ago
I am looking to get the "HMF Competition Complete Exhaust". The title says complete exhaust. I do not see complete or full system exhaust anywhere on the description. I am looking to get this exhaust for a 2003 TRX250EX. Will this purchase include the header pipe as well, making it a "full system exhaust"?
MotoSportExpert

A: Yes, this is a complete exhaust. When HMF designed the Honda 250 EX exhaust, they noticed a very small horse power gain with only a slip on system. Since HMF only sell pipes that make horse power, they only offer the Honda 250EX in a full system. Whenever you add an after-market exhaust system to your machine, tuning your carburetor is, in most cases, an absolute necessity. I recommend getting a Dynojet jet kit as well.
