Brand new, still in original, sealed packaging, Mitsubishi F8TJ0071 control unit. This is for the homolgated exhaust which I believe still had a catalytic converter but was freer flowing with a more characterful exhaust note I found a used (damaged) exhaust with the control unit on eBay for £340 which is a fraction of the £1400 new price, just for the control unit. Also found a few exhausts being sold in Germany and Italy, supplied without the control unit for around the £900 mark. Bargain of the day (if you have a first gen Diavel) £300 posted, Andy
