austin racing dyno results with just their gp2 system with no pc5 or filter,pretty good results but still slightly down on a bmw s1000rr figures with similar system..??? they gained 8 bhp over the bike with stock exhaust so the stock figures are under 180 bhp stock at the rear wheel so quite a bit down on the claimed kawazaki figures .....still very good though.....
nice looking exhaust system......:thumbsup:
