Just bought my 99 silverado with the 5.3. Im a diesel guy so i dont know much on gas but looking for an exhaust and want to find the best, loud sound there is. I was thinking glasspacks but heard some say they dont sound good on auto trans

 

Glasspacks don't sound bad on these 5.3s. Lots of people run em, 8" glasspacks/bullets will be pretty dang loud
