Get extra ground clearance during extreme angle climbs or descents with this Large Bore-HD Hi Tuck exhaust system for your Colorado, Canyon, or ZR2 2.8L Duramax. With its unique patent pending intercooled tip that reduces exhaust gas temperatures by 40%, this system is perfect for the off-road enthusiast.

Constructed out of 3" mandrel-bent, 409 stainless steel tubing, this system is less restrictive than stock, allowing for maximum flow and low turbulence, improving power and throttle response. OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.

This exhaust system is finished off with a 4" hi-tuck tip that is developed to give you extra clearance during extreme angle climbs or descents, protecting the exhaust over rough terrain. It features a brushed stainless steel finish and patent pending intercooled design, that reduces exhaust gas temperatures by 40%.
