Hi guys,
I owned a Gtti and want to make some modification on it like Cold Air Intake System;Cat-back exhaust system; Replace header; Mild Camshaft & Cam gear; High Performance Throttle Body; Light flow intake manifold; Larger Diameter Downpipe; Brake system, Turbo & Intercooler system and Electric system.
I've found Camskill website,but not really helpful, so I hope are there anybody done by other Gtti specialist on GTTI.

thanks
