Sounds great. Much quieter than my old Flowmaster. Very well-built in appearance. Made in America!

I installed this on my 2019 Sierra Denali and got the exact stealthy Magnaflow sound I was looking for. Better flow, quiet at morning startup, and throaty when accelerating is why I continue to put Magnaflow on everything.

The quality of the muffler is top notch. Having the muffler installed 1/15. So haven’t got to hear it or see if there’s any performance improvements. I have a smaller magnaflow muffler on my other truck and it sounds awesome. I did buy a larger muffler this time hoping for just a little quieter sound. One truck is a work truck and the other is not.

Exactly what I wanted for my silverado. Great sound when you get onto it. Noticeable increase in power and better gas mileage. My only regret is not buying it sooner.
