Amazing sound, I can feel the added horsepower and a increase in mpg,(After one fill up) after installation.

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.
