IIRC Draxas.com has them. i would think you'd get a CEL if you gutted that too, but i know of one person that did it. But yeah, that sulphur smell means your cat is about to go, which led me to buy the Brullen Y with the high-flow cat. Figured while i'm replacing the cat i may as well replace the y as well.
If you just gut the "big" secondary catalytic converter you run the risk of actually hurting overall performance.
Why? Because now you have a big empty chamber in your piping where the exhaust gas flow velocity can slow down and temperature can cool off. These both adversely affect exhaust gas scavenging; hence, performance.
I think catalyst "test pipes" are available for like $100 from TruBendz. You can probably can find a new Magnaflow high flow cat on ebay for not much more.

be prepared to pay a hefty fine if you get caught with no cat

There is a chance the Sulfer Smell is being caused by the Cat-Converters located on each manifold. Gutting these will net ~5Hp.....its basically a free mod w/o any negative side effects...Then replace the large cat under the car with a highflow cat converter. (or a straight pipe)
However using a straight pipe (eg; not having cats) will result in Rasp in the high rpms.

i just got mine for $80 on ebay... magnaflow hi-flow, stainless body, and with one, you will have a chance of passing emissions, something you wont without one.
I live in CT so there running the emissions with the registration. if you dont get tested, you cant register. so i went the safe way!
Ebay listing I bought from

1999 and 2000 are the ones that need MIL eliminators. 2001 and 2002 DO NOT.
The 99-00 has 4 oxygen sensors, and the rear ones MUST HAVE MIL eliminators to keep from getting a CEL.
Speaking from experience.
UNLESS the 01-02 have a sensor behind the cat - not sure about that...

What you're seeing is one Cat Converter and one resonator.
The main converter is, as mentioned, behind the Y-pipe, just behind the engine. The other two "precats" are hard to see, because they are buried. One is right behind the radiator, right next to the oil filter. The other is on the back of the motor, right next to the alternator.
were are all these sensors located 1 ineach precat but were are the other 2. i just looked under my car and unless the sensor it on the very top of the pipe there is none behind the cat or in front of it because in front of it is a funky looking mess pipe (not sure what its called) there was none on eather side.unless it is pointing straight up i didnt see any.
