Product Details

The FMF Q4 HEX Spark Arrestor Slip-On Muffler represents the next evolution in off-road exhaust technology. Constructed from aircraft-grade aluminum with a stainless steel end cap, this hexagonal muffler delivers exceptional performance while maintaining strict sound requirements for trail riding and racing.

Advanced Quiet Technology:

  • Intricate internal chambers and baffles optimize exhaust flow
  • Proprietary multistage packing material reduces sound output
  • Meets USFS and FIM World Enduro sound regulations
  • Well under 96dB sound output on most machines
  • Power gains throughout the entire RPM range

Premium Construction:

  • Hexagonal aluminum canister for durability and style
  • Stainless steel midpipe and oval slant-cut end cap
  • Pounds lighter than stock exhaust systems
  • Rugged design engineered for off-road endurance
  • USFS-approved spark arrestor included
  • Made in the USA

The Q4 HEX slip-on muffler is designed for riders who want maximum performance without the noise. Less sound equals more ground—perfect for maintaining access to noise-restricted riding areas while still feeling the power where it counts.

Note: Not CARB approved for use in California on pollution-controlled vehicles. Race use only in California.

Very easy website

It was easy

I expect everything to be ok. Hopefully, this will be a wonderful shopping experience.

It's was quick, simple and easy to find the parts for my car.

Good

I have to say I was skeptical at first because autoplicity's price beat everyone by so much! Then I estimated my shipping charges with their system and that too was real cheap for this heavy item I ordered! I ordered it on Sunday and it showed up on Tuesday afternoon! So exceptional pricing meets exceptional shipping and my item is the real thing for a lot less leaves me completely satisfied with this company! I will be recommending them to my friends and family, thanks!

I was trying to locate a hi volocity radiator fan and for it at Autoplicity at a very good price. The item was shipped fairly quickly concidering it most likely had to come from the manufacturer. Thanks for your help.
