Yeah, decats on petrols are illegal. You may be able to get it through an MOT with a friendly tester, but won't stop you getting in trouble if it ever got questioned. Worth it though

Looks lovely man!

Curts right and the simple way of getting around it is normally fit a decat then just change to a cat for mot but a lot of police now are catching onto this and looking under cars for decats. Simple solution - Take shitty aftermarket cat (not the genuine one, if it still works, they are worth a fair bit and becoming rocking horse poo), gut it and weld a straight pipe in. Job jobbed.
