I had a 9000 pro street on my canned 6.2 and it was obnoxious. It sounded completely different but was annoying loud.
I have a 9000 ready to go on mine. But I'm hoping with the cats and a full tailpipe out the back it won't be so bad. They do sound awesome.

3030 put my old dual Spintech setup on his truck when he split his muffler. It was obnoxious loud. I'm gonna be running his old cam, but in a stock 5.3 with a single pro street 3" in dual 2 1/2" out. It should sound pretty mean.
