Ok. So i just got a 2001 GTI; 2.0L Turbo 4 Cylinder with a turbo exhaust, cold air intake system, and magnaflow catback. I want to know what else i can do to make it go FASTER or look sweeter. Any ideas?
Hate to be pedantic, but a 2001 Golf would be a Mk4, and they didn't make a Mk4 2.0L Turbo. It'd either be a 1.8L Turbo (150 or 180bhp as standard) or a 2.0 8v (115bhp).
http://www.parkers.co.uk/cars/specs/Summary.aspx?model=1031Easiest way to make a Mk4 1.8T faster is to chip it, will see you up to 200bhp before you need to do other mods. Then you can upgrade the Turbo.
If your car is the 2.0L 8v, it's not quite as simple but you can still chip it for a small increase in BHP.
As for exterior mods, look at some 18inch alloys and lower it too. Keep it clean, don't clutter it with add on sticky bits.
