it is the stainless powerflow one that used to be on docfrags coupe. duplex with decat! this is worth at least 150 quid for starters! you have to cut the rear towing eye off to fit this but its not that hard! dont know why you want to change it though james as these are very rare and offer excellent performance benefits with the decat fitted as the turbo spools up a lot quicker virtually eliminating turbo lag????? a standard exhaust would cost you at least that and last 3 yrs max. the stainless will probably outlive you!!!!!
