how do i know if the CAT OVERTEMP PROTECTION is active? I had a local shop make a Y pipe without cats, but i do have simulators. do the sims take care of the cat overtemp or not? My truck has a nice new smell coming out the exaust, almost smells rich. Is the "COT" going to kill gas milage? How do I turn it off other than with EDIT? damn im full of questions!!

Here is what I did. It sounded great when open, but I noticed absolutly no difference between cats or no cats when the cutouts were closed. When I took the cats off, I could see right through them anyway. Not worth it IMO.
