This Kooks High Performance exhaust system is designed to maximize power and exhaust flow for GM's modern truck and SUV platform. This complete kit includes 1-7/8-inch primary headers and a 3-inch catted Y-pipe, providing a direct path for exhaust gases to exit while maintaining emissions compliance through high-flow catalytic converters. Every component is handcrafted in the USA using T304 aircraft-quality stainless steel to ensure long-term durability and corrosion resistance in even the most demanding environments.

Kooks systems are dyno and race-tested to verify performance gains across the RPM range. The precision-engineered mandrel-bent tubing and high-quality collectors ensure a perfect fit and optimum scavenge characteristics. This kit replaces the restrictive factory manifolds and Y-pipe to unlock the full potential of your engine.
