Perfect sounding muffler!

Summit RacingSummit Racing Verified Purchase

Installed this on my 03 Silverado 2500HD 6.0L. Was worried about how it would sound but it's amazing. It has a nice low rumble at low RPM's and a great sound when you hop on the gas. No terrible crackling at all. Noticeable performance increase paired with my intake and computer tune. I'd recommend this muffler to anyone!
