3 Exhausts in 1
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.
The Competition Series distributes power evenly throughout the entire RPM range.
Three exhaust inserts are included to give the rider the ability to quickly change the power and sound according to the riding conditions.
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.
Each HMF Competition Series exhaust system comes with 3 inserts that effect the power and sound differently. Stage 1 sets dB levels in the low-to-mid 90's, yet produces industry leading power at that dB level. Stage 2 insert sets dB levels in the mid-to-high 90's and produces substantially more horse power than Stage 1. Stage 3 insert sets dB levels in the high 90's-to-low 100's with industry leading power throughout the entire RPM range.
