I never understood why zzp is so popular if they always refuse to make custom parts for people before I did manage to find some one to make me custom headers back 3" straight pipe exhaust I asked zzp if they would make it and the response I got was just simply nope we don't do custom work so why do people like them so much if they only offer generic run of the mill mods granted I still don't have my exhaust on but that's due to a waiting for cash flow to get the BNR tune done at the same time and my GFB atmospheric blow off valve to arrive from Australia
