Description Item #HMF0006

Arguably the highest performing after-market exhaust on the market, the HMF Competition Series is a pure blend between optimized performance and versatility. The secret to it's power lies within the Trimax Core. This unique triangular core accepts specially designed exhaust inserts that provide the rider the ability to quickly change the power and sound according to the current riding conditions

  • Designed and tested for dirt bikes and ATVs.
  • The Competition Series distributes power evenly throughout the entire RPM range.
  • The Competition Series uses a mechanical core to control exhaust pulses and set power levels where they're needed.
  • The exhaust shell is made of T6061 Aluminum that weighs substantially less than stock.
  • Included with every exhaust are 3 removable inserts; the Trimax Core technology features 3 levels of power and sound, allowing you to dictate the type of power and sound you need, when you need it.
  • Trimax Stage 1: Uses an insert that restricts sound levels extensively yet produces industry leading power at the approved dB level.
  • Trimax Stage 2: Uses a different sound-altering insert that partially lowers sound levels without losing the power increase gained in Stage 3.
  • Trimax Stage 3: Acts as an unrestricted core producing high dB levels with industry leading power throughout the entire RPM range.
  • Features a black powder coated exhaust shell, stainless euro end cap, rivet bands, and the HMF team sticker for a completely upgraded look.
  • Packed with high-performance glass wool packing.
  • Includes installation instructions.
  • Includes a USFS-Approved Spark Arrestor.
  • Includes a 2 Year Limited Manufacturer's Warranty.
  • Manufactured in the U.S.A.

Great exhaust

Overall I love this exhaust. I put it on my 09 yfz450R. Sounds really good, I would like it to be slightly deeper but it still sounds great. When I put the system on the new head pipe rubbed on my clutch cable and one of the coil springs on my rear shock so I had to take it back off and dent the exhaust and bend it slightly but it ended up working out. I love the way it looks and am pretty pleased overall.
