My buddy had the N1 Dual on his '91 T2 and it was pretty loud when you got on it. What do you have in front of the N1? Stock? Downpipe, etc? If I were you, just keep the N1 setup and get the silencers for it. If you don't have anything in front of it, go w/ a racing beat dp and ps and you'll be fine. I have the RB downpipe and ps on my GTX right now...its hella HELLA loud..oh wait, I don't have a catback yet..maybe thats why

As for the HP gains from RB..they are legit. There systems frees up like 3 to 4 psi of boost and that alone is worth its weight in gold! I think they claimed like 2 to 3 psi, but I've seen a stock '87 T2 with JUST the RB turbo back exhaust and it was pushin 10.5 psi easy!
