Just wondering if anyone out there has taken out their catalytic converter and how their truck reacted to the change.

 

I left them off of mine when I put in long tube headers and full hew exhaust. You just have to either have them custom tuned out with Diablo or SCT and/or use non-foulers to trick the rear O2's into thinking the cats are still in place.
