The Large Bore HD Performance Cat-Back exhaust features 4" 409 stainless steel tubing with smooth curves and increased size to help remove restriction and keeps exhaust gasses flowing smoothly. The OE style band-clamps and bayonet style hangers make sure this system installs cleanly and easily. You will see increased performance and lower EGTs from this system. This system does not come with a tip.
