some argue it won't make that much difference to smal engines due to back pressure or summats, search for de-cat and i'm sure you'll find the threads.

the only reason i didn't do this was because of damaging the cat with removal and refitting, stuff was pretty coroded when i fitted my new exhaust i was tempted tho!
Made a nice difference on my 1.4 16v Sporting. and yes it will make it loud! unless you put a baffle box in between (very advisable) unless you like talking to police alot. Saying that mine was built into the manifold and removing it mean't putting a sport 4-2-1 manifold in its place.
