what kinda exhausts are you guys running, and how are they??? looking to get a cat back, but i’m having trouble finding…everything is either for 92-93, or for 2drs.
the greddy mx or sp will work with minimal modification from the muffler shop. i suggest you get one and have them install for you.
So there is a differance in exhausts for the 2dr’s and 4dr’s? What’s the differnace?
only difference is maybe an inch the most. you risk melting your rear bumper a tad like me unless you get the muffler shop to do a little bending. 
Can’t you just extend your piping? Like make your piping a little bit longer? Or is bending the only way around this problem? So you CAN use any 2dr exhaust tho right?
you can choose to extend the piping or bend it. whatever you like. i had mine bent cuz it was the easier way. actually it was the tip, my trust tip was too high so i had that extended out a tad.
I have a 92 sedan w/ an HKS Hiper exhaust on it. I had to get a 3 inch SS extension after the resonator because it wasn’t long enough. (it was for a 92-93 2dr)
The sedan is 2-3 inches longer than the coupe, and the 92-93’s are 2-3 inches longer than the 90-91’s. HTH
