i took mine to my local mot center to see what the damage was come mot time and i was pleasantly suprised at what i could get away with. seems the emmissions were well under the limit (no fuelling upgrades YET) and even though its a late '92, aparently i dont need a cat so its a good job i binned it!, he said he doesnt have a decibel meter so as far as he was concerned the noise level was ok even though its got a 3" system from turbo back with one pointless box where the cat used to be and he revved it up and it popped and back fired like a trooper and set a car alarm off on one of his other customers cars across the other side of the garage. he doesnt have a light meter so he's ok with the limo black window film (not fitted by me before you all start)and my odometer is screwed up but he said that wasnt a problem either.
