Just as a heads up, the PC3 is going to be phased out and the PC5 will be the one taking over. Just got an email from their Tech stating this. I too am trying to get the things needed for my full exhaust upgrade (HMF) and doing research. Seems it's getting harder to get Gen1 stuff.
So make calls and research everything, including tuners in your area and what they work with, before you buy.
Best of luck on finding your full Akras.
