They do make more (or did make more) than one exhaust. I had the Apexi R in my '95 R with supercharger. It was an awesome exhaust. I'd snap one up in a minute if I found one. Unfortunately, they are very rare....to my knowledge, sideshow was the only or one of the only people in the us to have an apexi exhaust.
i didn't get it when i got his car, so idk where that is now.
idk if they do more than one exhaust either, so i might be way off in my statement.
but yeah, srsly...jdm shiz brah.
