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

I ordered these but was wrong pipe, didnt come with the 3 incerts to change power and sound
this is a very nice system . light weight and sounds good
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!
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
This exhaust has the best HP increase on the market you can instantly feel the power gains as soon as its installed best purchase ever
I really have to brag about it. Has great sound and adds a kick to the power it already has
ADDED THIS TO MY SONS 2001 HONDA 250EX ALONG WITH A MOOSE JET KIT (ALSO FROM MOTOSPORT ) WHAT A DIFFERENCE ! BEFORE THIS HE WAS ASKING FOR A BIGGER QUAD, NOW HE I SATISFIED WITH THE ONE HE HAS ! THANKS FOR ALL THE GREAT REVEIWS THAT LEAD ME TO THIS PURCHASE.
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.
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!
Love my new exhaust. Everyhing was there and received it quick.
Would defenately like to thank motosport For a great shopping experience.
