I have recently purchased a full system scorpion exhaust for my clio 16 valve but am disappointed with it. There is no difference in noise or performance and the centre box seems to hang down under the car so it catches on the road alot of the time. I need to change this and was wondering what anyone would recommend me getting. Does anyone have an opinion on a magnex or mongoose and is there anything i need to get to make the exhaust fit better?
