<{POST_SNAPBACK}>Sounds like it is going to have to be a cat replacement. Although I'd suggest your friendly local garage confirm this if you haven't had it confirmed already - perhaps even take it to the MOT garage and ask them to put it on the CO2 machine.
If it does need a replacement then you have three possbible choices (unless anyone else knows of another suggestion) ...
1) Ford replacement cat - typically about 600cpi - costly
2) aftermarket replacement cat - either 100 or 200 cpi - not as costly and you get some performance gains
3) go second hand - which could be a standard one or sports cat. Several members have exhaust bits in the for sale section on here - in fact, one chap selling an unused sports cat (incl. downpipe).
You can do any of the above without going the full down pipe, cat replacement and cat back but you'll find a fair few members go this route anyway.
thanks mate, its starting to become more 'reaceable now, while your here, what about bringing down my insurance from £460?
