I plan to get a CAI for my 2006 ZX4 and after I plan to upgrade the exhaust system. Mostlikely with FocusSport. My only concern is I live in a green state, MA, and the vehicle is an everyday driver, so it must pass inspections. My engine is the D20E - 2.0L Duratec PZEV. If I put on the FocusSport exhaust system would I run into issues with this not being legal in MA?
