  1. MKIV GTI
    Hey guys, I just got my first GTI, consequently my first car and I have a few questions about proceeding with modding it. 1) Before I do a cat-back exhaust, do I need to upgrade my downpipe? 2) Where does it redline/where can I get a chip for it? 3) How can I get it lower without spending too...

    I just purchased a 2003 GTI 1.8t. So this is really a simple question. What chip gives you the best bang for your buck, or maybe just best performance gains in general? I just made the switch from a motorcycle and honestly I'm pretty clueless.
