I'm absolutely sure I purchased the right cat back exhaust for my 2017 GMC Sierra Denali. The 6.2l V8 creates a nice growl but is not overbearing. You know it's there when you put the accelerator down but subdued on the highway. The 5 inch tip is a nice touch and sets the visual tone to exhaust system. The system is "just right" with no drone and no issues when the truck converts to 4 cylinder operation. I recommend without hesitation.

Overall, very pleased with the Magnaflow exhaust. Two of the four hangers were off a bit and had to be adjusted, but I am a perfectionist. They probably would have been fine but now they are perfectly aligned. Exhaust has a very nice throaty sound when accelerating and quiet when cruising. Has a pretty good rumble when starting cold. Not too crazy about a five inch exhaust tip. Kind of makes it look like a diesel truck exhaust. The more I drive the truck with this exhaust, the better I like it.

Awesome addition, great sound, a little tough for one person, but only took a few hours to complete. Sticks out a little further than original, but still looks great.

This system went on by myself in no time at all. All of the hardware was dead-on. The sound is great and with the resonator it still keeps the cab noise down. Overall performance was quite a lot you can feel the Lo-end torque. It is just a great system a bit pricey BUT! you get what you pay for and this set-up was well worth it. Thanx Magnaflow
