Cat Delete Question

To the guys that are running cat deletes or know more about it than I do, how do you keep the check engine light off and it running normal?

You would need a tune to turn off the rear o2's as well as COT protection. Mil's cannot compensate for COT.

So the only answer is a tune. What is COT?

Yes only a tune will work. They don't even make Mil's for these cars I believe.

COT=Cat Over Temp

Is the COT read by the o2 sensors? How do you protect that? And the guy I spoke to on AM said they don't make one but they are out there.

The best thing to do is get a tuner, and have them turned off in the tune!.. Plus a tuner will help compensate in the tune for the additional exhaust flow, there for giving you even better performance!.. MIL Eliminators are mostly junk!..

Like Eturner, just get a tuner and have a tune made to turn it off. Plus you'll have the tuner for any future mods!
