For those of you with factory early sport mufflers:

I have an extra muffler off my 67S that I am planning to make the dual out sport muffler out of. I have done this a long time ago and have found the old Up-Fixin that shows the basic steps.

My question is: how long are the pipes?, what OD/ID are they?, should they have deco caps, painted or SS? how far apart (center to center)?

I would like to make them look as original as possible. Also, any hints or ??? would be appreciated. Photos are also great.

Vielen Dank!
