Thank you for your help
I have found the Flowmaster part number 389-17139 kit and 65-72 PONTIAC LONG BRANCH MANIFOLD DOWNPIPES DGF10S.
You stated that you used Dynomax mufflers. I studied an exhaust test for mufflers by Jim Hand from an old article. I liked the Dynomax model that was the best flow and less sound. Is that what you meant by using Dynomax instead of mufflers that came with Flowmaster kit?
Were you satisfied with exhaust tips and rear exit with no contact with body or vibration contact?
Thank you again for taking time to help me. I have been trying to get this done for many many years, and finally put myself up to ask for help.
