NDT was designed to take the most popular bolt-on modifications into consideration. This cat-back exhaust kit features 3” diameter piping, straight-through muffler, quarter-wave resonators, quad split rear exit and black chrome-finished 4” tips for an extra sporty appearance. The exhaust system is made entirely of stainless steel and was designed from the beginning with weight and ground clearance in mind to improve durability and maintain your 2021-2024 Chevrolet Suburban/GMC Yukon XL’s utility. CNC precision robotic manufacturing and mandrel bent tubing allow for hassle-free bolt-on installation. MagnaFlow stands by the reliability of their products with a limited lifetime warranty.
