Hey I just had a question about the Invidia N1 exhausts you sell for the 09 WRX. One is the "street" version and the other is the "race" version. Now I just wanted to be 100% positive about this... the "race" one isn't a turbo-back exhaust right? It's a cat-back but it just doesn't include a resonator like a normal cat-back or the "street" version? Just wanted to be completely sure on what the difference was.
