I have a 69 roadrunner and I am running headers with 3 inch collectors and pipes with a crossover pipe ran through a pair of Dynomax turbo mufflers with turndowns at the rear axle. I am contemplating running the exhaust all the way out to the rear bumper and installing some 3 inch road runner stlyle tips I have spotted on ebay. I have an electric fuel pump and filter mounted onto the inside frame rail on the passenger side.
I am curious as to whether any of you performance minded Moparites are running large diameter exhuast and if any problems exist. Thanks!!!
