# Magnaflow 2021 GMC Yukon XL / Chevy Suburban / Cadillac Escalade ESV Street Series Cat-Back Exhaust

The MagnaFlow Chevrolet Suburban/GMC Yukon XL Street Series Cat-Back Performance Exhaust System #19543 drastically improves your 2021-2025 Chevrolet Suburban (Premier/High Country) or GMC Yukon XL 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 Suburban (Premier/High Country) or GMC Yukon XL 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 2021-2025 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.
