I just had my ART headers installed. Now the Mark makes WAY too much noise. I have to tip-toe around and still attract too much attention. The sound is harsh and unpleasant. It's got to go! I've had an ART cat back system with x-pipe and Edelbrock RPM mufflers that sounded great but now I need to add a third muffler. Does anyone have any suggestions?
Edit: The cats have been removed.
