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!

Installed these on my Pontiac G8. The exterior sound is a nice rumble. not too loud, not too quiet.The interior noise "drone" is rather noticable but not too terrible and has a little vibration to it. Again, not terrible. Nothing a little sound dampener cant fix.
