Its not illegal but will fail MOT if it hasnt got a cat when its supposed to. Any car after a K reg should have a cat.
To get a better noise out of a car the best bet is to get a performance exhaust - cat back would be best for you if your worried about removing the cat

You can take the middle section out but all it will do is make it raspy.
Will also be losing back pressure by removing a silencer

what the hell is back pressure? you would never want any sort of pressure in the exhaust, you want the exhaust gas to be removed from the cylinders, not forced back into them!
