OP herefordshire location?? get yourself down to prospeed in cardiff and get a quote. the guys sorted me out with a cat back quad system. fitted it all up at less than £500 including a flexi pipe and replacement gaskets on the down pipes. i've been back twice since as 1 gasket failed and the down pipe had a leak, and although not connected to the work they did they sorted it out Free !! next year its back for sports cat and downpipes all for less than £350. good proffessional service and aftercare.
give 'em a call
