@mb911 - I heard your heat exchangers and quiet muffler on Coondog's ( @coondog ) car at the Phoenix Club show a couple months ago. My brother was with me standing at the entrance gate when Greg pulled in. We both agreed his car sounded perfect.
I caught up with Greg a little later in the morning and discovered we had identical drive trains and exhaust. 3,2 with Motronic, 964 cams and a Steve Wong chip and of course your full exhaust system. So I am very very very much looking forward to hearing my car and driving it.
