Turbo mufflers typically are close to OEM sounding as they have the S bend piping inside and arent designed to be aggressive in any way. Simply out flow stock, thats about it. 3" pipe on a stock 5.7 is typically pretty quiet in itself. I had a 3" straight pipe dumped out the side of my Sierra and it was quieter than my current setup of 2.5" stock pipe with gutted cat with a Cherry Bomb Extreme. Also I should note the Extreme muffler is rated louder than the glass-packs on their scale.
