Have you looked for the pre-cat? Shouldn't be too hard to find out if you have it.

They can help you with RHD parts.

 

I dont think the down pipes are universal , meaning RHD to LHD. Because the stearing shaft runs between the precat and fender. I think Knight sports sells one that has two tubes so that it can have more volume but does not have to be wider.

 

Since your getting a new DP and wish to keep under hood temps down, you might want to consider having the DP heat-coated and/or wrapping it prior to installation. This will also significantly reduce those temps.

 

The Japanese cars do have a pipe with no cat where the American pre-cat would be. It is still restrictive, heavy, etc., but looks kind of like a cat with the heat shielding and everything on it.

I'd probably just get the HKS downpipe - it's easy to get, very well built, and was designed for right-hand drive cars, so it will fit your car great.
