ah, sorry, i genuinely was confused, it's true though, for example in Japan they sell 80mm exhaust for civic's, try and find even a used one in the USA and you will see what i mean. I tried to search for top fuel parts a few years ago when i was still working on my car and this is what i discovered. Aside from going directly to an importer here really is no way."bitched down versions" doesn't constitute as "their stuff". I figured you would understand what I meant.
