The price was a bit crazy in my opinion $350 but other than that I have put around 500 miles on the fmf q4 so far on my 1998 klr 650 and I love the look of it, the sound is just right and it feels like the bike has a bit more power too! I'm glad I got the fmf q4 muffler.

Pipe fit great with no issues. Sounds great. Louder Han stock but not too loud. Also install the FMF joe-jet kit so not running lean
Good directions, easy install on Suzuki DRZ400S. Sound and noise level is good with spark arrester installed. Also installed K&N air filter and stage 2 jet kit. Good power increase in mid and high rpm.
I am debating which pipe to buy and install on my 2014 Honda trx450er! All I have installed is a UNI air filter and put a 130 jet. This ATV is like new and wow the power I got from a jet,airfilter change! I gotta buy a slip on muffler and jet kit! I live and ride around the National Forest and thinking this muffler and a JD jet kit is what I need/want!
Sounds great. Not too loud but has a great pop at idle and cruise. Had to re-jet the carbs. Runs great.
Easy install, it took less than 30 minutes. It really opened up my XR650L. I highly recommend this slip on exhaust!
The finish of the Q4 muffler is very good. However, the fit has the muffler
touching the rear fender. (just slightly) I added a small spacer (along with the supplied spacer) to get a little more clearance. Can't comment on performance or durability yet.
What an amazing purchase this was, with the easy install and the great sound you cant go wrong.
Awesome pipe, super easy to install, smoothed out the power band on my 06 yz450f, nice and quiet and makes my bike off road legal everywhere, will be putting FMF pipes on all my future bikes.
I just bought a new crf150r and i mostly ride trails and around the neighborhood. I needed something to make this bike more quite and have a spark aresstor so i got this. overall i think this purchase was a great one, shipping was very fast and free, I would defiantly recommend this to a friend.
The FMF Q4 Spark Arrestor Slip-On Exhaust has a Max Sound output 96dB; most models below 93dB.
