exhaust down pipe

was doing a bit of searching but cant find my answer, so wanted to ask 2 things
98 gt555 irish turbo, does it have 1 cat or 2. i was going to get a custom made down pipe from turbo to decat car, but the guys said that 2 options are showing up for my reg plate, 1 with 2 cats the other with 1.
also the crowd i was going with are souhan exhausts have any of ye heard anything bout them

I think it has 2
one in the down pipe and one in the mid section
at least my 2000 version did
just buy a down pipe on here off someone would be a much cheaper option than souhans
Wagon Dec has one for sale
