I agree seems to be the consensus between all the performance shops. I know folks that have Camaro SS's and their's either melted too or where gut'd and they had all the best name brands.
Problem, here is it's pointless to purchase them if you plan on increasing HP to some degree and / or use a SC, however, your damned if you do and if you don't. It's illegal most places not to have them, so you have to waste money to purchase them and have them gut'd to maintain the illusion that the vehicle is legal.
In my mind the question is; Why don't the manufactures provide a product that will hold up to higher cubes as they already know most peeps in the mod arena are usually building high performance engines on vehicles that are daily drivers as well as week-end warriors at the track? Or is this just a limitation of current day technology?

Ted advised me I'd likely burn out my cats after he so graciously increased my car's performance to its current levels. In retrospect...I should have asked about before the install but don't know if there is any legal restrictions to shops installing off-road pipes on street cars. I plan on doing it as soon as I get my Christmas presents. Oh how I wish a lift would fit in my garage!!! I may have to sale my place and find a bigger garage...

So extra fuel helps to burn up the cats quicker? How do the COT spark and fuel tables help to combat this? Better yet, can the COT spark and fuel tables help with this?

[camaro1]

a shop cant legally even install long tube headers with cats, the cats are not in the original location and also its illegal to remove a good catalytic converter, and can face fines of $10,000,, i guess all the shops and people have been lucky so far that the govt isnt really cracking down yet.


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 original2. 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

Fuel is used to Cool the Cats, I find many tunes with COT turned off, I never do this when cats are attached.

It is Not so much the fuel than the Volume of exhaust gas that needs to be converted.

The cats would need to be double they're current size to handle the flow and do a good job of converting.

Why doesn't someone make a CAT that is double, is there not a market for this item?

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Check the Price of the cats for the ZR1 or CTSV

I've seen this a few times already. I still don't know why people run cats with a blower cause it's not a smart idea.

[Oxtar41]

When I bought my long tubes I was told not to even waste my money on highflow cats because the S/C will destroy them. This was from a very reputible shop and sponsor here on C5.

Just for kicks (and hopefully someone can explain the process), what about the blowers that have CARB approval? How could they get the approval if it was known to destroy cats?

Factory cats are More resilient than aftermarket cats and at 5-6 PSI it is not a problem.

thanks Ted. Good to know. All the talk was a little concerning.
