in general you only loose 2-5 bhp on a cat so is it worth it
also it will fail the mot if manufactured after 1990

i have a decat pipe, when it comes to mot time, im gonna see if i can get away with putting that stuff in my car that lowers the emissions,

when i ran a saxo vts for sprints i put de cat pipe in which was the same length as cat and fitted cat back in for mot
otherwise failed every year on burnt out cat due to over fueling with the L.A.D, msport engine in

its not just emissions, they will check its there!

you really, really do not want a straight through exhaust system.

it will make your car slower, and louder. you need back pressure for a n/a to work properly, loose this, you loose all the power.

de-catting it aint a bad thing.
