Got this done on mine a couple of days after I got the car. As mentioned it's a slightly deeper exhaust tone, pulls a little better. Luckily my mate (and mech) has done quite a few of these so knew to get it hot to avoid snapping anything.. Definitely worth doing, mine was taken out before gutting to avoid blocking the main cat with anything left over

Does turbo noise increase a bit with the cat material removed?

They are piss easy to remove crack them all off when the turbo is hot!

Just bare in mind the clamp that joins the cat to the middle sectiion, the nuts are usually pretty rusty and round easy be worth getting 2 new bolts ready or a new sleeve incase you need to cut it.
