Loss of power

[rescuer3]

Thanks. I am going to try removing the O2 sensors and run it just to see if that helps before I actually cut into the exhaust. If it does, I will replace the front 2 and either hollow out or remove the 2 rear. It will be a while before I get the time to do this, but I will post what I find.

I would not remove the front O2's because the engine uses these to determine the fuel mixture that is injected into the cylinders.

Thanks, I guess I will get parts ordered then.

Update; Got the new cats installed today ( front only, deleted the back) and the differnce is amazing. Got the power back and fuel milage is as good or better than before. Thanks for the help.

Hi rescuer did you replace front cats with oem or aftermarket. I am in nc as well and am interested in the rear cat delete. I just don't want to start chasing emission codes to get my 05 inspected. Thanks Stuart

It has been almost 2 months, no codes or other problems so far. Cats were replaced with high flow from Eastern. I did weld in a bung for the rear o2 sensor so it is still in place.
