I love the sound of the Flowmaster Super 40 Series mufflers. The classic muscle car sound they provide is second-to-none.

Ok Honestly, I like my exhaust pretty loud. Before this muffler I had muffler deletes on my 2005 GTO! It sounded good but at idle it had kind of a splat like sound and not a good tone. WOT sounds awesome! BUt lets get to this Super 10 Muffler by FLowmaster. It's not as loud on a Stock system but, it is loud! The difference I like about this muffler is my torque was a lot more stout with this muffler and the tone is so deep and sounds, seriously awesome on my 2005 GTO. Best muffler I've bought!
