BRExhaust 106-0344 is a direct-fit replacement exhaust system for 6.0L V8 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks, replacing the factory pipes and muffler from behind the last catalytic converter back. The mandrel-bent 3.5 in aluminized steel pipes bolt together in several pieces, so it installs without bending, cutting or welding.
