You would be better served getting an exhaust system just made up at a shop in the UK, or better yet get a UK system. By the time you hack up a US exhaust to fit it's going to run you the same.

The body kit will not fit at all, don't bother...in the end you will have better luck and spend less money getting a UK kit, if one exhists. If you have to have US look a like parts just get a nice tasteful universal fit spoiler if one exists.

As for the intake good luck, I don't know about those.

I'm not trying to be a hater or anyting but unless you have a UK coupe parts just aren't going to swap. And your money is better spent on other things...maybe even buying a car that can actually use US parts like a UK Civic Coupe (I think our Si was your VTC or someting) from the late 98-99? era or an Accord Coupe 98+ or Prelude 97+.
