Thanks for the responses guys. I really appreciate the help. I’m trying to loosely recreate the outward appearance of the original dual pipe system and only hope it produces a sound that could be described favorably. A nostalgic touch of the homemarket, I guess.
Carl – The Magnaflow example you found is the closest to the original muffler I’ve seen so far. I will find out if they can be had with 2†inlets and outlets. The original has a length of 12†and the Magnaflow has an 11†or a 14†length.
Alan – I’ve seen your photos many times while doing searches. There are not many other examples to be seen. I think I even dreamt about your stainless system once or twice. I can replicate the pipes for the intermediate and rear sections from the original intermediate I have and from photos of the rear section. I do need a little help with the “booster†dimensions. I don’t know if it is possible to see the perforations in the through pipes to get an idea of, how many holes there are, the size of them and the arrangement. Also I’m left wondering if there is a single expansion chamber for both through pipes or is it divided in half? Please don’t put yourself out, taking it out of storage and measuring. In this case close is good enough.
