Eddie44 Posted May 24, 2007 Share Posted May 24, 2007 If you have a C6 automatic is it an A6 (paddle shifter)? What exhaust do you have and do you get an unbearable resonance at cruising speed? I'm being told the A6 does this because of the low RPM level it runs at. I'm desperately trying to find an aftermarket exhaust that give good sound w/o the resonance.
