Hi Buf-Phoon. Thanks for the response and the clarity on the issue of ex cop cars. I will also try to remind my mates that these cars aren't chipped or modded! Anyway...my goal is to update the air intakes, exhaust, install hi-speed cat, new chip, but keep the engine bay as factory appearence as possible (as I quite like the standard engine appearence). Looking forward to catching up with other XR6T lovers and going for a SE Qld spin sometime. Cheers, T-Sweet.
