hi iv had a 1.0l lupo for a couple years and iv lowered it and fitted some wider wheels but i couldn't see the point in making it any faster. but i just bought a gti lupo about a month ago. its completly standard but will be getting kw coilovers and some wide wheels (not sure what yet) i want to modify the engine to get it a bit quicker and the first thing will be the exhaust system. so any ideas? iv been looking at the scorpion cat back system so if anyone has any reviews of them would be useful. cheers
