please help 97 cobra catalytic converter delete

[97cobranm1]

I have a 97 cobra which needs new o2 sensors and cats but I would like to find a kit to simply remove cats and replace with downpipes and new o2 sensors and a chip to take full advantage of the more open exhaust and run properly car already has a loudmouth cat back and cold air intake also where I live in NM there are no emissions or noise laws so doing so would not be illegal but cant find such a kit for my car

There are many choices of mid pipes in H or X style. Just Google 1997 mustang mid pipe.Off road style have no cats and can add a few hp.

Yes but it does not run or respond well without cats and kits I find do not have chip or programmer to correct computer to run right

You either need O2 eliminators or a tuner to correct your missing cats.
I currently run no cats and it runs just fine. Sounds nice too.

Just so you know... While NM may have no laws requiring inspection of emissions systems, removing cats is against federal law. So it is in fact illegal.

Hmmm....removing the cats should not affect how the car runs. Perhaps you didn't get a o2 sensor plugged back in or you have a bad one. The front two o2 sensors are the ones to be looking at.

My $0.02, a CAI is a waste of money on a car with a stock or non-boosted engine. Some of the so called "cold air" actually leave the filter in the engine bay sucking in"hot air"...

@cbrown I was wondering about that. I had my air filter box and MAF out today in order to clean the air filter and I couldn't see how a CAI would help since the stock setup pulls cold air from inner fender. I do wish there was a way to eliminate the upper section of air tube that has the indent for the strut tower brace without removing the brace.

@OP As others have said, get a off-road X of H pipe and then just run it like that or better get a tuner like SCT X3 and you can do a simple strategic tune with the device to eliminate the rear 02 sensors (there is no need for the narrow band rear 02 sensors if you don't have cats).
