quick4dr Posted June 23, 2012 Share Posted June 23, 2012 Currently running a catted cnt dp with stage 3 efi tune. About to swap to FMIC and ewg, worth it to go cat less? My last car had no cats so I know about the odor and increase in exhaust rasp, not worried. What would actual power gains be. Any input welcome Link to comment Share on other sites More sharing options...
scoobyscoodle Posted June 24, 2012 Share Posted June 24, 2012 I think they would be negligible going from a high flow catted to catless. If you want a different sound/smell, or are changing the setup anyway pick your preference. I don't see you making more than 3-6whp at most.
