exhaust and filter will add almost naff all to car performance.spend your money on a track day course.the fastest ,best driven car ,i have ever been in was a standard 1.6 montego ,driven by a man who could really drive,any half wit pratt can go fast in a striaght line.but i you as a average guy want performance,chuck everything that is not needed,ie rear seats,air bags,door panels,spare wheel,passengers,etc.how fast do u want to go,or are you just spouting hot air
