No i have fitted one yet, i might do in the future, but i cant see it making much difference, The exhaust is a Nur spec, but it is abit big, might be changing when i gather some money, Im looking into either the 4efte or 5efe conversions at the mo, going more towards the 5efe and then wack a turbo on it when i can afford the insurance. And also might have a glanza rear axle coming, if i can afford it. Jack
