Noise control is possible thanks to MagnaFlow’s No Drone Technology (NDT), which uses quarter-wave passive noise cancellation tuned to the specific droning frequency of your Chevrolet Tahoe High Country or GMC Yukon Denali in order to eliminate exhaust drone. 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 Tahoe/GMC Yukon’s utility.
