i have failing cats and its throwing codes does anyone know of a O2 sensor delete or a tune that i could get, i really dont feel like payin $5000 do get all new cats and o2 sensors.

 

all 3 cats went?? how many miles and year of car??

 

Just replace with a straight-thru pipe, with extended O2 connection.
That'll keep the sensor from seeing too much oxygen in the exhaust gas.

Alternatively - parts train (all one word) have cats around the $350-400 mark.

 

The 2 primary cats are part of the header so it will be a lot of work if these went out. If its the 3rd then you can go aftermarket or delete and not be ULEV but you will need the o2 extension Like This but if you have a visual inspection in your state you will fail and get fined.

 

Not if your the one inspecting it lol
