Just check 2" inlet and outlet on your down pipe, the Veccies are.
2" may go inside the cat but considering the original when cutout will leave around a 13" piece missing, extension pieces will be required to mate up. Tack weld on car else flexi wont last two minutes.
Other than that track down Ashley, they do the same cat as piccied here for £90, its on mine. They do the round and flat type, below is the flat.
