The new HMF Competition Series exhaust was designed and tested for Sport ATVs and Dirtbikes. 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 3 removable inserts, each of which effect the sound and power in different ways, giving the rider complete control.

• 3 different inserts for 3 stages of power and sound. (All 3 included)
• Tough, heat-treated shell with the HMF Team Sticker on the side.
• Stainless steel rivet bands for a sharp look.
• Designed and developed for Sport ATVs and Dirtbikes

• The Competition Series is available in Black T6061 Aluminum.

• Depending on the model of the machine, the Competition Series is offered in both Round and Elliptical shells.

• The Euro End Cap is standard on the Competition Series. The shape of the exhaust will dictate which end cap will be installed.

• Depending on the model, the Competition Series is available as a Slip-On and Full System.

• Stage 1 Insert: Sets dB sound levels in the low-to-mid 90’s (varies per model), yet produces industry leading power at that dB level. Not recommended for extended use. Re-Jet/re-Map accordingly.
• Stage 2 Insert: Sets dB sound levels in the mid-to-high 90’s (varies per model) and produces substantially more horse power than Stage 1.
• Stage 3 Insert: Sets dB sound levels in the high 90’s-to-low 100’s (varies per model) with industry leading power throughout the entire RPM range.
