alright heres my question if I cut out my cats would i have to change out my oxygen sensors. Right now I have eldlebrock headers shorties and a ravin muffler dumped. Im just trying to squeeze a few more horses out mabye . what are your thoughts. And mabye a little bit better and deeper sound

 

No, but unless you want to drive around with the SES light on, Id get teh codes turned off in the tune, or get some simulators for the rear O2s
