thanks for reply's guys.
i should of made myseld more clear, the exhaust was an example, i have seen parts like, aftermarket pods, silicone hoses, radiator pipes, fuel flters, fuel pumps etc. that say it is for GTT or GTS-T, i would like to know in general if all these types of parts fit/will work with N/A skylines (r33, r34) as well.
Sorry for not making myself clear everyone! hope question makes more sense now.
Cheers.
