11-18 GM 2500HD Pick-up 6.0L V8 3 1/2in Cat Back MBRS5076409

If you're running a 6.0L V8 in your 2500HD, you already know the engine's capable of serious output—but a restrictive factory exhaust system is holding back both power and sound. This cat-back system replaces the factory muffler and resonator with a straightforward 3.5-inch stainless steel design that reduces backpressure and lets your engine breathe, while delivering the aggressive V8 tone that comes with genuine performance upgrades. Whether you're towing heavy loads or pushing the truck hard, you'll feel the difference in throttle response and overall efficiency.
