just welded the EXACT same muffler on my buddys 04 5.3 last week and dumped it, i like the sound WAYYYY better than my flowmaster 40 series dumped. sounds almost stock at idle but when your drivin its not loud nor quiet and its throaty sounding...then at WOT its louder than i thought it would be by far. would have deff got one of them instead of my 40 series if i went back to when i did my cat back:imo.
