It turns out my Japanese spec 92 Gen3 is called a Type-R.It has Bilstein suspension,twin oilcoolers,suede seate,deep lip front spoiler and rear wing.They also come with rear seats and rear wash/wipe.The jap ones dont come with airbag either.Here in England we dont need a cat to pass our annual emissions test.Anyone have a cheap/easy way to eliminate the cat?will it improve overall performance?
Any help much appreciated
Thanks guys,Rotarybrit

 

Got any pics??? just to be curious if it looks any different on the exterio/interior, then the american version...

 

If you do not need the cat, you should not need the pre-cat.
Replace both with a DP(down pipe) and a MP(mid pipe). But then you will need a reprogrammed ECU or Apexi PFC to add more fuel. You could only replace the pre-cat with the DP and leave the cat in. This would not necessitate the need for the upgraded ECU.

 

I have a jap import and they do not have a pre-cat. But an afterarket downpipe does have a bigger bore. Remember you cannot fit an American downpipe as it does not make an allowance for the steering rack.
