Do I need a tune after cat Delete?
Tuning is required after removing catalytic converter to ensure the car’s computer (ECU) is calibrated and provide you with the most performance. Without tuning to calibrate the ECU, you will likely face these issues: Check Engine Light (CEL) is on.
Do you need a tune for no cats?
You will either need a tune or O2 sims, otherwise no it will not run right. Wrong. The rear oxygen sensors do not affect the way the car runs at all. The CEL will constantly be on, but that’s it.
Where does the exhaust tip go in a catalytic converter?
These components do exactly what their names imply. A Cat Back system bolts to the tubing that exits the catalytic converter and usually includes mufflers and some form of outlet tube. In many cases, the exhaust tip is attached to the end of the cat-back system.
Can a catalytic converter be repaired without replacing the ECM?
Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. A careful search might reveal exhaust leaks that, when repaired, “restore” catalytic converter function, at least from the point of view of the ECM.
How are cat back and axle back systems attached?
Axle Back systems bolt to the mid-pipe tubing as it passes over the rear axle of the vehicle. Both Cat Back and Axle back systems may attach to a natural break in the system or could require cutting the tubing as some point. In most cases, these kits use a clamp to fasten then in place but can also be welded if the customer requests.

What happens if you remove catalytic converter on GMC Truck?
If your truck is a 1996+ and you remove the catalytic converter, since there is a pre cat and post cat sensor, the ECM/PCM sees no difference between the 2 sensors outputs and turns on the SES light. You will be fine so far as the ECM and OBD1 system.
