The ATP 3", stainless steel cat delete pipe for the Evo X is designed to bolt up between the stock or an aftermarket 3" downpipe and a stock or aftermarket catback exhaust. The ATP Evo X test pipe has two O2 bungs making it easy to hook up a wide-band. The race pipe is for off-road use only and is not emissions legal. Removing the cat is a surefire way to free up some power in your Evo X (ATP says 30 ft/lb of torque and 15 HP on a mildly tuned engine).
