I've heard some good things about that and the hi flo kits by researching around a bit but i also hear that once u hand them a deposit they take thier timemaking your kit because they are "busy" so some people are very pissed off at hi flo right now idk about gmr but it sounds like a really nice kit personally if i ever go that route id go with a single turbo though
