About HMF Engineering Competition Series Full System
HMF Engineering Competition Series Full System
- Designed and tested for dirtbikes and ATVs
- 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
- Included with every exhaust are 2 removable inserts, each of which effect the sound and power in different ways, giving the rider complete control
- Stage 1 Uses an insert that restricts sound levels extensively yet produces industry leading power at the approved dB level.
- Stage 2 Uses a different sound-altering insert that partially lowers sound levels without losing the power increase gained in Stage 3.
- 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.
