Fit and finish are good. But it is QUIET. Can’t tell any difference from stock except on start up. Any other time it sounds the same. This is on my 2019 5.3 Chevy 1500.

Sounds great on my 2015 Silverado 5.3L but I thought it was going to be a little louder.

Perfect for my application, sound is way better than a megan racing muffler that only had a couple months of use. No fart can sound on my b20v setup.

It sounds great. I have a Ford 4.9 (inline 6), and it's not the fastest, but with the flowmaster and a Y-pipe off of the manifolds, you can finally tell a difference in power and sound.
