the cat on the r18's are right up/kinda below the engine bay persay..the cat's on the Si's are underneath the car in a "high flow" type design more back off the headers..this being because the r18's arent placed the same as the k20's..r18's being the wrap under style headers or w.e u wanna call them...this is exactly why u arent seeing alot of catbacks for r18's yet and just alot for Si's..other reasons being that its just easier for the companies lol not that they want to cater to the Si's 100%, thats just some of it..but id have to say installing a catback on the Si's is hella easier than on the R18's..not that u cant reach the cat cuz its not like its tucked up anywhere unimaginable but from what ive seen its easier to reach the ones on the Si's rather than the R18's
correct me if im wrong please.
