Unleash the Growl: High-Performance 4-Stroke Racing Exhaust
Transform the power profile and sound of your machine with the Universal Parts High Performance Racing Exhaust. Engineered specifically for high-displacement 4-stroke engines, this system reduces backpressure and improves exhaust scavenging, allowing your engine to breathe deeper and rev more freely. Finished in a sleek, high-temp black coating, this canister provides a deep, throaty exhaust note that signals true performance on the track or the trail.

Mechanic's Note: When upgrading to a high-flow exhaust, your engine will run leaner because it’s moving more air. Pro Tip: To prevent overheating and popping on deceleration, you MUST increase your Carburetor Main Jet size. Pair this with a Performance Intake for a complete Stage 1 power upgrade!
