Thanks, I will check out the buick muffler and see if there might be a problem. The rather quick drop in temp. at idle was something to think about. When I called Klass Kollection exhaust they said they could make up any lenth of muffler I wanted. The 1933 owners manual shows the car to have a very long muffler and a resonator in front of it. If I find a problem with the buick muffler I can have them make up a longer one the right size etc. Thanks for your help guys. Doug
