I have done multiple searches over about a weeks time and have found nothing about people who are running cutouts on a full stock exhaust before the cats. Has anyone out there done this? and will it throw a check engine light on the after cat sensor? Also would the power difference for this type of setup even be worth it? I admit right now my experience with exhaust is limited but I do know that 2000+ for a new full exhaust system is not in the cards. Any input appreciated.

I'm pretty sure I posted on this a long time ago. I'm running Kooks Headers into 2.5" cutouts before the cats. I've had my computer reprogrammed and haven't had it throw a code while using them yet. My rear O2 sensors must have been disabled in the computer patch.

The cutouts are good for .5 seconds in the quarter.

Cheers!
