did this last week, swapped cinq sporting onto a sei abarth. you have to give the front section a 'tweek' to clear the petrol tank as it makes it way back, what i did was use the last but one hanger in its standard position which moves the tailpipe towards the centre of the car by about 300mm, and then weld an extension of about 150mm to the final back box hanger - not too bad a job, sits tight to the mesh section of a abarth/ sporting rear bumper but doesnt bang and gives pleanty of clearance for speed bumps etc:slayer:
