The car has a considerably lower, more audible grumble from deleting the resonator. My car next to 32Krazy!'s SLK sounded great; a nice night and day comparison. I want to either remove the muffler or replace with a louder note. The few passes that have been recorded of my car only pick-up the high pitch wine of the S/C. Very cool in its own right, but I need a baritone to mix with it, lol.

PS the ECu is very good at adjusting for minor changes to the system, so doubtful that releasing a bit of flow on the back end will show a disturbance in the force.
