Universal Parts High Performance Exhaust - GY6/CN250

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.

Technical Performance Features

• High-Flow Straight-Through Design: Minimizes internal restriction to maximize horsepower and torque gains, especially on modified or "Big Bore" engines.
• 102mm Oversized Canister: The large-diameter outer shell (approx. 4 inches) provides ample volume for sound dampening without sacrificing flow velocity.
• Heavy-Duty Construction: Features a reinforced 18.5-inch overall length designed to withstand the high vibration and heat cycles of 150cc to 250cc powerplants.
• Universal Mounting Kit: Includes the essential mounting hardware and bracketry required for custom installation on a wide variety of scooter and kart frames.

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!
