Hi, does anyone know if a high flow cat downpipe would fail MOT in the UK? I'm trying to get a Stage 1 remap done with pops and bangs mapping, but I know the OEM downpipe won't be able to cope so looking to change this.

Don't you have Noise Laws in the UK?

I think so but just found out removing any cat is illegal, so looking at the option of doing a res delete or a muffler delete.
