My assumption would be that a sport cat is less restricting than a regular cat, yet still reduces emissions at a legal level

Thats what I was assuming Tim, i'll ask before I buy though cos they are pretty expensive. Furthermore, decatting is so obvious with the smell of the fumes entering the car behind you and grey smoke belowing out like crazy. The plods bound to stop you if they follow you and slap something on you (or I defo would've done it)
