Hey guys, i'm really liking the Invidia Catback for the 06+ Si. I emailed hopupracing, they said they have it in stock, but they haven't tested out the decibal level. I'm waiting on the decibal test, before i am sure that i'm going to purchase. I like Invidia, and have heard good things about them, because i know a couple people that have STi's and have Invidia exhausts, and DAMN do they sound good. Well anyways, what you guys think?
