Ok so i have a 2015 Suzuki swift live in the UK.

i want to get a decat but afraid it will fail the M.O.T due to emissions.

I just had the MOT done and it passed however if i get it done will i have to replace the cat back on every MOT.

and how hard is a CAT to put back on, i know a back box is simple but does the CAT have to be welded back on??

I highly suggest if where you live requires emissions you do not touch your cat.
