I just bought the Catco cat from Summit Racing. It is 3" in/out, part number cto-6007.

Please be aware that it is 14" long and the stock cat is around 24" long. You will need about 10 inches of pipe. An exhaust shop should be able to take care of that without a problem.

I have a 99 and the o2 sensor is not in the cat. It is after the cat. I am unsure about the 2000's. If you just get a cat and not a cat-back as well you shouldn't have to do anything with the o2 sensor, except get a o2 sim.

I just got the texas speed rumbler as well and the place that installed it had to weld an o2 sensor bung (or whatever it is called) so they could install the o2 sensor.
