Leave the stock cats on the car and run a K&N drop in air filter. I feel that this combination will keep the noise level right where you want it and maximize your performance given the mods that will be on the car...

Thanks, Tony
Not to completely derail the thread but....Tony, you've mentioned adding K&N drop ins in a few threads now. Have you dyno'd any gains with them? Many have said they don't add anything at all, but I've never seen data to back up claims either way.

Thanks, and back on track after Tony answers
