The Big Gun Evo Racing Series was designed to deliver maximum horsepower and torque gains throughout the RPM range. Made from 0.049" stainless steel tubing and an aluminum muffler canister, the Evo exhaust system is much lighter than stock units. The sleek muffler design also allows for maximum clearance to avoid your exhaust from hitting the rear brake caliper.
Super lightweight stainless steel header.
Extreme power and smooth torque delivery.
CNC mandril bent 304 stainless header for exact fitment and precise airflow.
Meets the strict AMA 102dB noise limit.
Available in complete systems for MX bikes only.
Note: All Big Gun exhausts are for closed course use only and are not intended for use on the road. Big Gun exhausts are NOT LEGAL for sale or use on pollution controlled vehicles in the state of California.
