FMF Racing Slip-On Q4 Muffler with Spark Arrestor: $359.99

A day before my first off-road race ever, I was a nervous-wreck because of many reasons. One reason I could pinpoint was that I knew the pipe on my 2004 Honda CRF250X was no where near sound legal. In the AMA-regulated National Hare & Hound Series, a bike must be no louder than 96db and is subject to sound testing. FMF equipped my race bike with a Q4 Muffler and spark arrestor insert, which calmed my delicate nerves and pre-race stresses a good amount. Honestly, my bike was so loud before it just felt like I was constantly hitting the rev limiter and going to blow up the bike with even the slightest twist of throttle. After installing the FMF Q4 muffler, I could feel and hear when my bike needed to be in the next gear. If your bike has a stock pipe, this muffler will enhance your power and if you have a loud pipe, this product will allow you to save your hearing and deliver smooth power while complying with noise regulations.

The aluminum muffler slips on your stock header and after bolting it down you are set up with a fresh performance mod. Weighing in at 5.4 lbs, it’s not lightest muffler option in their lineup but it is the quietest. Overall, the FMF Slip-On Q4 muffler was easy to install, delivered smooth power and gave me the peace (and quiet) of mind I needed.
