Just curious if anyone knows if the cats on Jap and Aus S2000s are the same length or not.

I know that with my old EK, the Japanese cat-back I purchased had a longer B-
pipe, so I had to fit an aftermarket cat. Will this be the same scenario with the S2?

i think they are the same because when i installed the cat back exhaust it fits right on.

did the cat back exhaust give you any CEL qk2000 with the standard ecu?

Edit: or did you change the ecu at the same time as the exhaust?

wat is CEL? as i have changed my exhaust system too, and just resetted the ecu by unplugging my battery terminal

cel = check engine light (on the dash)

I think I missread qk post sorry
test pipe usually throws "cel", you will need a simulator
i am not sure if the high flow cat will cause this or not


so szooo_r, you had no problem after a cat back exhaust too?

Has anyone had a high flow cat? did it throw a "cel"

qk2000

h9k, no CEL.
