I just bought a tsp rumbler cat back exhaust for my 97 LT1 formula my question is since this car is basically going to be a fun strip car for the weekends can I remove the catalytic converter without running into any problems with the computer ? is their sensors that plug into the catalytic converter on a 97 LT1?

Not sure i had my cats taken off when they installed my headers i thought they put different o2 sensors on. My check engine light does come on i took to my buddys shop and hooked it to the computer and it said o2 sensor wich he said is normal for everything thats done to the car wich wont hurt a thing i dont no if a tune would help u but id get it tuned anyway just for the extra hp. But ya if i were u id get a set of longtubes and y pipe and dump the cats itll breath alot better and pic up some power

Your obd2 car will probably throw a code if you delete the cat because of the rear o2's. I would send the pcm to a tuner to get rid of the rear o2 data in the pcm.

www.lt1pcmtuning.com www.pcmforless.com

www.madtuner.com are 3 places you can send pcm off to get tuned. Obd2 tuning software is expensive, so I can't reccomend the do it yourself route.

best way to tune an OBD-II once you start removing emissions stuff:

- obd-i ecm $100 (hawks third gen)
- tunercat definition $30
- cable $60 (aldlcables)
- resistor for the knock sensor: $0.50

you can have it all converted clean in less than an hour, costs about as much as a mail order tune, but you gain total control over it yourself
