There still is the primary centre CAT, in my case an upgraded Supersprint hi-flo sports CAT.
The remap was done at the same time by Autodelta so emmisions are all kept under control as you would expect.
No refitting of exhausts required, car sounds great.
I know a few guys that have cut out the pre cats and have had a few problems with lambda sensors causing error messages. Ive heard this has happened with the supersprint manifolds aswell.
