I have a brand new in the factory packaging universal comptech muffler. the inlet is 2 1/4" and the outlet is 2 1/2". There is no tip on the muffler, so it would be perfect for a ef or da as it sits, or you could easily weld a tip on it and put it on anything. The muffler dimensions are 14" long x 9" wide x 4" tall and is fully polished. I was planning on using it on my ek hatch, but have decided to go a different route. looking to get $100 obo, i'll try to get some more pics later on.
