Just want to get an opinion to why some SC owners get their cars de cat on front pipe.
Are there any advantages, disadvantages?
Will it affect the MOT test when the car needs one?

Thanks for your replies in advance

P.s I'm up this late cause it's tooooooooooooooooooo hot to sleep .

its the pre cats that are removed



less restriction on a restricted system as standard
pre cats break down



no the pre cats are only for initial cold starting
the mot test is done with the engine warm


you can go to bed now
oh the joys of an air conditioned bedroom
