Gibson quality, good welds, can tell its well made. A little louder than I thought it would be but works well

I had a 40 series flowmaster single in/out with stock tailpipe on my GMC 5.3, it sounded good at idle but disappeared at WOT when I really wanted to hear it, so I bought the super 10 to replace it, I dumped it right by the rear axle, this thing sounds amazing, exactly what I was looking for, I find myself flooring the gas peddle just to hear that amazing exhaust rumble. I couldn't be happier and if you are scared it will be too loud, don't be, it isn't super loud, but it is deep/aggressive.
