Welcome to the site mate. As far as i know you will have to get any exhausts bits that have been modified back to standard, the oil cooler is an aftermarket part, I think you will be ok with the brake discs and wheels, but your priority should be the exhaust. is200 and altezza exhausts are the same from the cat back, but different from the cat to the manifold if i remember correctly. Hope the search for standard parts goes well for you! I might turn out cheaper to by a standard one in any colour and spray it yellow afterwards! :shutit:
