if you want to drive it on the road it will. You might be able to get away with no cat but it won't give you anything. The exhaust system on the S2000 is designed for a certain amount of back pressure and the presence of a catalytic converter, removing the cat changes the dynamic. Naturally, YMMV but I wouldn't recommend removing it.
