My 2004 GMC Yukon Denali XL 6.0L muffler hit the mark. After a week of sounds like the car was about to explode, I decided it needed repairs. I looked at the range of mufflers on the Revain website and decided this one would work for my application. I was expecting to be as big as a standard Mรผller and was a bit reluctant to have the shop weld it. But as soon as I started the car after installation, I knew it was the right choice. Much quieter than the stock muffler but still sounds great. I am more than satisfied with this damper. Would buy again.
