I did the same thing that you did, what 5 years ago. I still have the thread saved to my PC. The mufflers 22" X 3.5" outside, 3" inside with the thermal mat, were $208.00 each from SS, Mickmate a poster here on Cobra Club did the welding for me and they are at the Jet Coater right now. Unlike you, I am going to leave the baseballs out of the pipes to get the flow numbers up.
