MACH Force-Xp 3 IN 409 Stainless Steel Cat-Back Hi-Tuck Exhaust System GM Colorado/Canyon 15-19 L4-2.5L/V6-3.6LThis MACH Force-Xp Hi-Tuck cat-back exhaust system exhaust delivers pure power and sound. In testing, the cat-back exhaust system resulted in gains up to +9 horsepower and +10 lbs. x ft. of torque, as measured on our in-house dyno (tested on 2015 GMC Canyon V6-3.6L). Made of 3" mandrel-bent, stainless steel tubing for maximum flow means the smooth transition bends and free-flow stainless steel muffler allow for low turbulence, increasing horsepower, torque and improved throttle response. This exhaust system is finished off with a Hi-Tuck tip to give you extra ground clearance during extreme angle climbs or descents protecting the exhaust over rough terrain.
