Designed and tested for 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.

Inlcudes a USFS Approved Spark Arrester.

2 Year Limited Manufacturer's Warranty.
