2012 A7
I want to attain a more "throaty" sound out of my A7's exhaust. What exhaust system will give me the deepest/lowest/meanest rumble?

If you really want "the deepest/lowest/meanest rumble" swap your engine out for a 600+ cubic inch big block Chevy V8. lol
Seriously, the basic noise an engine makes is dependent on engine size, number of cylindrs, firing order, valve timing, and compression. Exhaust sytems can be tuned to enhance the sound quality, but they can never make a 4 cyl sound like a V6, or a V6 sound like a V8, etc..

Pete,

Thank you for the information. I realize that no exhaust will simply make it sound like it has a V8 in it. I just want to get the lowest sound I can with my current engine. I thought maybe someone had gotten the Stasis exhaust and heard it compared to another option, and could say "IMHO the Stasis Exhaust was a deeper sounding exhaust in comparison to the "example" exhaust."

Thanks again...

Anyone? Its greatly appreciated.
