Does anyone know the diameter (preferably in millimeters) of the stock pipe going into the muffler? Thanks!

i don't know for sure, but when you do find the answer, 25.5mm = 1 inch. now, i saw your other post as well, and can assume what youre up to. the only thing adding a muffler will do, is give you that sound, and no performance gain. if you already knew that, and thats what youre going for, ROCK ON!

Yep, that's pretty much it. You've just got an add-on Magnaflow muffler, too right?

60mm O.D., 58mm I.D. = 2.25" I.D.
I just measured the cross-cut end of my resonator, which is now in the basement.

nope, cat-back.

How did you get a Magnaflow cat-back system? Their website lists nothing for SAABs.
