I'm no engineer, but I can't imagine a CAT being good for power or mpg! I've heard all the backpressure theories, but I don't agree.
For example, mower and boat engines don't have CATs and they run just fine. Cars have CATs not because the backpressure they produce is needed, but because the EPA mandated it. How many CATs do you see on F1 cars, Indy Cars...see my point!

Think about places like Australia who have NO emission laws at all. Hell, you'll see 400-500 HP cars coming out of the factory over there just for that reason. The motors and exhaust don't need any thing to changed the output at all.
