It's simple physics. You can't trick your way around it.
Everytime you remove/change the exhaust, you lower backpressure. So you lose low-end and gain low-end. Any mod to the exhaust takes away from low-end power.

Removing either cat might lead to a CEL. Pulling out the first cat is pretty safe (it's like a cheap header). Removing the 2nd definitely leads to CEL (100%) and won't do as much.

The CEL is from the test pipe and won't go away. (Obviously, check to make sure - auto parts stores will scan you for free nowadays) The RRM CEL fix isn't perfect. It didn't work on my car.
