Hey I got a question. I have a 2003 SE-R and I'm trying to find some aftermarket stuff for it, but all I see are stuff for the Spec V, and I'm wondering if both cars use the same products such as catbacks, CAI, headers, etc...Also I'm wondering who makes the best catbacks for a 2003 SER, how much HP, torque it would increase?

everything that fits the spec will fit the base se-r (except for the short shifter I believe), and all suspension and body pieces from 00-03 are interchangable

Hey thanks a lot for clearing up so much for me.
