# Magnaflow 2021 GMC Yukon V8 6.2L Street Series Cat-Back Performance Exhaust System

The MagnaFlow Chevrolet Tahoe/GMC Yukon Street Series Cat-Back Performance Exhaust System #19580 drastically improves your 2021-2023 Chevrolet Tahoe High Country or GMC Yukon Denali by enabling MagnaFlow's deep signature sound and dyno proven performance to work their magic in improving your driving experience while keeping interior noise in check. 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 2021-2023 Chevrolet Tahoe/GMC Yukon'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.
