Rite, well i bought a gti twin exhaust off ebay for a tenner and was told by the seller it would fit my 1.3 as all mk2's are the same. Brought it to my local exhaust centre to have it fitted, came back an hour later and was told it wouldn't fit, i was also told that my old backbox was removed and they werent putting it back on. So had to drive home with no backbox and the car sounding like a tank

How easy willl it be to refit my old backbox and is there anything i can do to make the gti one fit??
