Can't answer your first question, but I can answer your second. Removing the secondary cats will not throw any kind of code. The 02 sensors are located before and after the primary cats, which remain untouched. There is nothing aft of the secondary cats, so nothing to measure and record, therefore no code.

Just so you are aware, removing the rear cats may net you 5 to 7 hp, you will NEVER feel 5 to 7 hp. you will never feel 10hp. Your a$$ is not that finely calibrated! a "general" rule of thumb is you pickup about 1/10 time with 10 hp addition. that said in a 400+hp car you don't even feel the a/c compressor kick on as you climb a hill and that topically takes 10 to 15 hp from an engine. What I am trying to say here is leave the cats alone, they are on there for a reason, to clean the air!

True... but if you remove the cats and get the JoeZ exhaust

You will feel the rumble...
You will feel a rise in your pants...
You hear what a true sports saloon should sound like...

You will not be disappointed ;)

True, until...you are fined for it.
It is illegal to remove a functional catalytic converter even to replace it with a new one.
It is illegal to tamper with emission-control devices. The Anti-tampering Law applies to individuals as well as to businesses. Individuals may be fined as much as $2,500 for each vehicle tampered with, and businesses are subject to fines of up to $25,000.

Technically business are not held liable for anything except for some faulty issues with the product. ALWAYS READ THE DISCLAIMER! They do state it for "OFF ROAD USE ONLY!" So basically if you use their product on streets then it's your own fault.

what a load of sh!t. fined. ha. i don't have to do any emissions check where i live. removing the cats probably nets a few hp agreed. more than that though it makes the car sound meaner. if i cared about clean air i'd wear birkenstocks and drive a hybrid.

how many old pos cars and trucks do you see everyday with a rusted out muffler dragging on the ground? you think they all get fined?

save your speech for someone else.

Catalytic Converter Laws

Rules for Replacing Converters
In 1986, the U.S. Environmental Protection Agency issued new guidelines for the construction, efficiency and installation of aftermarket catalytic converters. All CleanAir converters listed in this catalog have been designed, tested and manufactured to meet this policy.

In addition, CleanAir converter listed in this catalog is appropriate for use under the current requirements of the California Air Resources Board (C.A.R.B.).
E.P.A. guidelines state that replacement converters may be installed only in the following situations:

1. The vehicle is missing a converter
2. A state or local inspection program has determined that the existing converter needs replacement
3. Vehicles manufactured prior to 1996 must have more than 50,000 miles, and a legitimate need for replacement must be established and documented
4. In cases of OBD Il-equipped vehicles (1996 and later), the O.E. manufacturer's 8-year/80,000-mile warranty must have expired and a legitimate need for replacement must be established and documented.
Please note that Federal law prohibits removal or replacement of a properly functioning O.E. converter.

When replacement of the converter is appropriate (as outlined above), the E.P.A. further requires that:

1. It be installed in the same location as the original
2. It be the same type as the original (i.e., two-way, three-way, three-way plus air/three-way plus oxidation)
3. It be the proper model for the vehicle application as determined and specified by the manufacturer
4. It be properly connected to any existing air injection components on the vehicle
5. It be installed with any other required converter for a particular application
6. It be accompanied by a warranty information card to be completed by the installer.

Of course, when did anybody ever enforce this? If you put free-flowing cats on a vehicle...WHO CARES!!! I have seen so many people change their cats however and whenever they pleased. Where in the U.S. do people actually get cited for messing with their cats if they can still pass emissions standards?

Personally, I am against vehicles driving on the street that can't meet emissions standards. There is no need to pollute the environment. On the other hand...emissions standards are EASY to pass if your vehicle runs properly. So who cares if every part of the exhaust is modified to be less restrictive.
