removing the cats will increase power every time.
we are not driving 1.6 liter four cylinders with 5 inch exhaust. our engines are a fair amount of big and the 2.5 inch dual exhaust is downright restrictive with the cats and exhaust manifolds in place. the mufflers don't make it one way or the other. still too much backpressure in the exhaust.
remove the cats and you still haven't reached potential. put on long tubes and you still gain power....
you aren't going to screw up flow with any of the available bolt on modifications available.
