Adding HFC's..

If I'm adding high flow 300cell cats to a catless x-pipe w/ 2 resonators, would it create more drone or less drone? I'm running full Gintani catless exhaust right now.

Not sure it will change the drone, but it will lower the volume and give you a slightly less aggressive sound.

Meh, the difference in HP will be negligible (less than 10).
