This is my exh system on my 63 which is 3" pipes with Dyno-Max Ultra-Flow mufflers and the headers are 1-3/4 tubes. I have never uncapped it but I think I will try it the next time I go to the track which should be Oct 24'th at Capital raceway in Md for a nice NSS show. Maybe I can run a new best. Ron
