I bought a pair of old Edelbrock 5501 stainless mufflers at the local swap meet years ago. When I went on line to find info on these things, I couldn't find a thing. Apparently the 5501's aren't made any more. I wonder what they sound like, what they cost new etc etc. They have 2.25" inlets and outlets inline with each other in the middle of the muffler ends. Anybody got a clue? Plan is to put them on my 34 ford with Pontiac 370 motor.
