Hello peeps, Ive just picked up my new v5 sti so far Im pretty impressed there is a few things need doing to it. First thing being the centre diff, the other being a new downpipe as its blowing near the join to the rest of the system, now this puts me in a bit of a situation I have a stainless decat but also have a standard catted one. Would I be able to safely run the decat without a remap or am I asking for trouble? Also is it a big job to change the centre diff Ive done a search but found no threads.

Thanks
