E60 M5 - Muffler Delete Before/After [HD Audio & Video]
since there don't seem to be too many Exhaust videos out there with high quality audio, I decided to take my rig out and capture some revs. (Canon 5D3, 35L and Zoom H4N for Audio). Muffler delete only. Stock headers, cats, secondary cats and resonator still intact. There's virtually no change in the cabin, very very little drone, and the overall tone at lower and mid RPMs is much, much nicer. It's actually not very loud at all -- I'll try to get some driving clips soon.
