Increase the chances on failing MOT on emissions, depends on other parts of the system but thats it really. Louder the better imo! If it still sounds good

i've done this on most cars which i've had, escort rs2000, fiat coupe 20vt and my current subaru. only one i had a problem with was the coupe. it needed the cat if still running a standard turbo due to back pressure. should be no trouble on your car though. i sure the cat restricts upto about 15% on a n/a car but more on a turbo. should sound alot more beefy too.
