yeah 500 sounds on the money.get some pacemakers which r expensive and a 2.25 inch exhaust with a good muffler not an el cheapo and u should notice a decent increase.
while mine is a 253 going to pacies and single 3 inch system over no name extractors and basic 2.5 inch system it took it from a generic runner that if u dropped the clutch at 4 grand it would spin the tyres but wouldnt go stupid.drop the clutch at 4 grand now and it smacks the 6800 limiter with ease.all from a decent exhaust
So some people are complaining about my motto on cops.well if u knew what ive been thru u wouldnt.so quit your whinging!
i hate cops!
