thats a right shitter that is mate
ok, somewhere there is a bit of info about cars built before august 1993 not having to be fitted with cats

so, if you can say that your engine is a pre august 93 engine you won't have to fit the cats to it

but you are in a bit of a grey area because as far as i know it only applies to uk cars

if you drive a 94 car then thats a moot point (i can't see the pics so i don't know what it is)
