Is there an actually company called, "JDM"? I always thought JDM were Japanese parts. for example, are Spoon header also allowed to be called as JDM header?

Im asking this question because I'm planning on a purchase of JUN header. But I'm open for any suggestions. As for the JDM header, i know it gives out the most mid to high end torque, but since the headers long i think i'll have some difficult problems in the streets of LA.

Im new to the form scenes and would appreciate for the help.

As for my cars is an 98 champ. Toda cams and camshaft, mugen head gasket, motor oil pan, mugen catback exhaust. full AEM water bypassed intake sytem, Tein suspension setup, and spoon brake pads. to this point I'm a very proud owner of 60,000 miles :lol:
