are all of them the same and interchangeable assuming its for a coupe? are the 94-95 different from the later years? and is there a difference between models like gsr compared to ls?

i am looking to buy an oem cat back exhaust and want to clarify it before getting it from the dismantle shop.

as far as the years go... 94-95 are obd1, and all 96+ are obd2, so the catalytic converters will be different (1 o2 sensor vs. 2 o2 sensors).

and i believe 94-99 are the same from the cat-back, and 00-01 are the same, but different from the 94-99.

what year is yours?

 

mine is a 94 gsr coupe. i have the headers and cat. just need the catback that will fit. i just talked to one of the places and he said all years were interchangable from the cat back and there is no difference in size, mounting hangers, etc between gsr, ls, rs. i told him i thought there was a difference and now im double checking it. i bought the car with aftermarket exhaust so im just looking to put the oem one back in.
