Coming Back To A 5.0

[red 92]

After having a 2006 v6 for the past 9 years and coming back to a 2013 v8, its definatly nice having the torque as well as exhaust sound again. Couple things I was wondering, is there anything you guys could recommend that I !might need to know about the 5.0? The previous owner removed the cats by the headers, thankfully they came with the car, my question is what are the performance gains from having no cats? The car is throwing a code because of it and am I better off just installing the original cats back into it since I'm guessing the gains are minimum.

The car seems mostly stock other than some exhaust and a k&n

I'm surprised this hasn't been answered. Have you figured it out yet? I'd say just tune the code out...if it can be tuned out. Not too familiar with the Coyotes.

Gains are absolute minimum, removing cats is such an 80's mod. These cars have high flow units form factory.
