Full System Exhaust

Mandrel-Bent Header Optimization & Scavenging Dynamics vs. Factory Pipe Restrictiveness

True engine power development depends completely on unrestricted exhaust gas scavenging. Our replacement ATV and UTV full system exhausts utilize precision CNC mandrel-bending processes to ensure that the primary header tubes maintain a perfectly uniform internal diameter throughout every complex bend. This smooth internal finish completely eliminates the restrictive exhaust pooling and turbulences common in standard, crimp-bent factory pipes. By maintaining a high, uniform exhaust gas velocity, our tuned exhaust collectors create a powerful low-pressure scavenging wave that actively pulls spent exhaust gases out of the combustion chamber, allowing your cylinder to draw in a completely fresh intake charge on the next stroke.

To withstand the brutal environmental exposure of deep water crossings, dense mud bogs, and flying trail rocks, our full system exhaust kits are constructed from thick TIG-welded aircraft-grade 304 stainless steel and high-tensile aircraft aluminum. These rugged, corrosion-proof materials expand and contract uniformly during rapid thermal shocks, completely preventing the brittle stress cracking that destroys thinner metal tubes. Featuring vibration-damping heavy-duty exhaust springs and reinforced mounting brackets, these complete pipe assemblies seat securely into the cylinder head, delivering bulletproof durability across punishing off-road terrain.

• Digital Fuel Correction: Recalibrate your engine's air-fuel ratio to match your high-flow exhaust by installing an electronic fuel tuner.
• Exhaust Body Shelling: Safeguard nearby body panels and wiring runs from header pipe radiation with an insulated premium exhaust heat shield.
• Tailpipe Decorative Exits: Finish off or refresh the trailing edge of your custom pipe track using an aggressive billet aluminum exhaust tip.
• Under-Engine Armor Plating: Deflect low-lying trail stumps away from your new header collectors with heavy-duty aluminum skid plates.
• Chassis Mud Protection: Deflect tracking trail mud away from your external exhaust springs using high-impact ATV and UTV fenders.

Exhaust Gasket Seating, Spring Tensioning, & Engine Remapping Protocols

When installing an off-road full system exhaust, always use a brand-new copper or crush-style exhaust port gasket at the cylinder head interface, as attempting to reuse a squashed, brittle factory gasket will almost certainly create a high-temperature exhaust leak that causes erratic popping and engine backfiring. Thread all cylinder head header flange nuts on loosely by hand first to ensure proper concentric alignment before slowly tightening them down in an alternating sequence to the precise factory torque specification. Utilize a professional exhaust spring puller tool to stretch the retention springs into place without scratching or kinking the metal loops, as surface nicks can trigger premature fatigue cracks under heavy vibration. Clean the entire length of the raw stainless tubing with rubbing alcohol before firing the engine for the first time to remove oily fingerprint stains, which will otherwise permanently bake into the metal as gold-brown blemishes.
