The "shorty" will weld to your cat. You don't even need to mess with your O2 sensor. However, you will still have the u-bend and you will need to pay someone to remove the u-bend (and then mess with the O2 sensor) if you really want to take full advantage of this.
The other option is a race pipe that is bolt on, but there is no cat involved...just a straight pipe which takes the place of your old cat. This has a bung for the O2 sensor, but you will need to buy an O2 simulator because it will throw a code since there is no cat. And, in some places with strict emissions it's illegal to run without a cat.
