Overview:

The MagnaFlow Chevrolet Suburban/GMC Yukon XL Street Series Cat-Back Performance Exhaust System #19543 drastically improves your 2021 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 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.

Easy to install and great value.
Model: 197mil 31 sqft Car Sound Deadening Mat
Very easy to cut and install with the rollers I bought separately. It adheres well even though I was installing it when the weather was closer to 40-50 degrees. Definitely helps to deaden the sound from the bare sheet metal.

Garbage
Model: 197mil 31 sqft Car Sound Deadening Mat
Straight garbage, I tried to cut corners on cost of building an spl car and should have stuck with dynamat or something like that. This is NOT for sound deadening…… Garbage product!!!

Sticks very good. Did a lot of things front and rear on my Polaris side by side. Seams much quieter and had enough leftover to do another one.
