Hi is Milltek the only company that makes sports cats?

Would i be better just getting a universal one and bumping it in the centre pipe?

Cos i have a Supersprint cat-replacment but the police have been pulling all modified cars over the last two weeks and i think you will get a fine if my emissions are too high. Which they definatly are!!

I know one of the traffic cops about here but chances are i will get pulled by another one!!
