First some background info:
I have an 07 2.5i wagon with an OEM STi catback. The tip on the muffler is a little dented and is starting to get some rust spots. I would like to replace it but am not sure what size the diameter of the outlet on the muffler is. I think its 2.75 ID? Can anyone confirm this?
If I get a new tip, what size should the inlet on that tip be?
