I finely got my exhaust installed. Hopefully I won't have to deal with that again for a long time. I have Dan's (ART) ceramic coated long tube headers, stainless 2.5" pipe (ART kit), large Magnaflow muffler (2 in, 2 out with x-pipe) and two Edlebrock RPM mufflers with large oval tips. It's quiet, like a stocker until I floor it. Then you can hear the power but it's not obnoxious. I've been running with the headers for a while and it's been so loud I could hardly think. Now I can enjoy the stereo again. This might be the setup for those who plan on having their Marks for a long time.
