im not just after the sound, im not allowed a turbo or super charger due to the crappy new laws for p platers. ive done the cold air intake, k&n panel filter, extractors, 2.5 inch exhaust, done the dizzy futher 22 degrees 8mm leads, so im jst looking for a legal way to get more power with out a huge price. im thinking either gilmores or vy ss 18's
