Password jdm has a jdm itr exhaust and says it is 2.35"...i thought the jdm itr exhaust was the still 2.25 in??? and it will fit an em1 (2000 si)?...Should I go the comptech catback or stay oem and get itr exhaust...I think comptechs is 2.25 and the itr is bigger but has bottlenecks right...???

 

It will fit, just the tip will be almost flush with the bumper....actually a little in I think if I remember the pics. Some one here posted it on his EM1. Looked awesome.
