Hi, i'm new to the forum and have a couple of questions about parts i was looking into, i'm currently running a 3.5" exhaust w/test pipe on my 05' Evo. Well here's my questions:

1.Does the JIC dp go on without any fitment issues?

2.Would it be advised to bump up to an evo 9 turbo? A buddy of mine is selling his, and i'm thinking about picking it up.

3.Which cams would run better for a daily driven evo: GSC or HKS, planning on 272's.

Main goal for now is a daily driven and at least low 12's. Hoping for high 11's but who knows. Any input would be appreciated, thanks.
