Hey guys sorry for late reply, issues with the notifications?!
All sorted in in the end, it was with a downpipes cat from factory, but it was quite a bit over the limit, but I found something online and after speaking to a few local Scooby experts who pointed me in the right direction, and if it's a pre '95 model plus being an import then by law it does not need a cat at all!!! So after finding this out I took the information back to the garage and showed them and then they retested the whole car and passed it with 0 problems!!!! But I did change it to a decat pipe now, well I might as well now it's allowed !!!!!
