Maybe this information is of no help to anyone, but here goes.
At our local Mustang car club meeting tonight, I made a specific point of asking one of our members who ownes two or three of the national muffler chain stores. Meike its called, but I may have spelled it wrong.
Anyways he is familer with the honeycomb cats breaking apart.
He does sell "high flow" 2 & 1/2 inlet cats as a replacement.
Yes he must also do the paper work certifing that the old ones were "bad".
He knew of two cases where they replaced the cats under warrenty and the manafacturer of the cats stood behind there product, no problem.
He said he could surely fit high flow cats to my truck if mine were bad and guaratee them!!!!!
Mine are OK but they are from JDM.
I guess its WHO you deal with that makes the big difference.

I heard that gutting them gives you a bad sound. I have straight pipe where the cats where before.
BTW: I have a dual Boral XR-1 Sportmans Race Mufflers with x-pipe and long tube header exhuast with all 2 1/2 piping. I scare lil kids
I say run without any cats -- straight pipe it. I heard you gain some hp but lose some lowend tq.

the technology of making these trucks fast. The cats just simply
dont break up for no reason at all and we are really asking alot
out of them. Leaky headers, bad gas, bad tune, and being
anything less than gentle with them will cause a cat to break
up. Not many street cars make 400,500,600,700 HP,
occasionally go to the track and actually have catalytic
converters. On the same note I know that Dons Bolt has been
driving on the carsound cats for the last 3 years almost and just
recently blew them out. Ask Don how many miles he has driven
on them I think its over 20,000 miles. We would like to warranty
everyones cats but carsounds is tough on having them
warrantied even for us, a vendor that does a high volume of
buisness with them.

Some of you guys just can't wait to get one more dig in against JDM. JDM does not make these cats, they resell them as do thousands of other performance and muffler shops across the country. Bassani has had the same problems with there cats and has also refused to warranty them, but I don't see you putting in digs against their vendors.
What ever your problem with JDM is/was, let it go and move on with your life. You'll be happier that way.
By the way, one of my cats also failed earlier this year after two years, 20K miles. I bought two new ones, (2 cats with installation totalled $300) and didn't look back. That's part of owning a performance vehicle.

that it is a dig, huh? Most parts for OFF ROAD consumption specifically
state that they are not for on road use and that there is NO WARRANTY.
Most race parts are the same ...
What I was pointing out was that nobody is telling the customers
that there isn't any warranty on the parts.
That's all ... Lose the drama, d00d ...

On a side note it is illegal to replace the factory cats with anything other that factory cats before 50K miles or something. I'd have to look it up exactly.
"Under Federal EPA regulation, replacement of original catalytic converters is allowed only if the original converter(s) is missing, or the vehicle has more than 50,000 miles or is at least five years old and the need for a replacement has been established and documented, or a local inspection program has determined the existing converter is in need of replacement."

What does this cat rattling sound like? I have been happy with the Bassani cats on my 2001 and 2003 L's (prolly have 20K miles on them so far) but I want to know what to listen for when they start to go south. Is it a rattle that varies in a regular pattern/speed with RPM, etc, or does it sound like rocks tossing around randomly in there? Metallic and tin-sounding? Or soft, muffled noises?
