honestly, i have no idea the process of legalizing jdm cars.
www.kansaimotorsports.com is who did it. i suppose they could help you out with any questions that you have. though they are kind of secretive as to what is required and what methods they use, they may not tell you much. they have quite a few rhd jdm cars, including a very nice dc5-r as the owner's daily driver. hes selling it soon for an s15 though. hope that helped.
back to my exhaust question......ok so im looking for eithor full stainless or Ti exhaust that isnt crazy loud and that has an angled canister. and apparently you guys say the jic ti is too loud. thats pretty much the criteria. price doesnt matter too much. but 1K is gettin to me a lil too much. eithor way, any suggestions? ive heard the invidia is loud as well.
