random tech. cats problem!!
I just seen what my rand.tech. catalytic converters look like inside after only 3000miles on them! the inner catalyist came apart and clogged up the driverside almost completly and the passanger sides center of the catalyist crushed my 02 sensor. my car was loosing power like crazy at VIR this weekend and now I know why. needless to say I would stay away from these high flow cats! mine are now really high flow as I made them into straight test pipes! just something to look out for and if you have them you might want to check up on them.

....for your health
That's not good. Was it a sudden drop in power or was it more subtle? Guess I'll be lifting my car this weekend to check them out. Thanks for the info Matt.

if it happens to the RT cats it happens to the Stock Cats...
how I messed mine up was going out to my car, turning it on cold, and just flooring it to show off the sound to customers etc... so dont do that to your car and yuour friends and drive it hard when its cold... you will get fuel on your cats...
fuel on cats being RT / Ken... / Cra... / or STOCK WILL Mess them up...
I have been running RT Test Pipes...

WTF! I just bought and installed a set of R/T cats a few weeks ago! I thought that this was a reputable company! Is this why Performance Nissan was running a "special sale price" on them? At over $500 for the set, if this is what I can expect to happen, this is a major rip off!

mine did not melt! they actually started to slide appart ( the material is wrapped around in a big roll ). the center of the "roll" started going downstream from the exhaust pressure and broke free from itself leaving the front side of the cat to collapse on itself blocking the air flow. and since i spent over 1k getting ready for this event and not even being able to run it, i would not even think about putting them on my car again!

there is nothing wrong with them... stock cats would do the same thing if they got fuel on them... but stock cats will be $795 each side to replace...

no melting accured. they just slipped apart. I am not bashing their product just wanted to give others a heads up that they might want to check theirs. i am happier with them gutted as they sound much better.

I ran the car at very low rpm's when i knew something was wrong and my mechanic checked the car thoroughly and it showed no signs of the catalyist making its way back in the engine. He also said it would be very doubtfull that the kind of material that random tech. uses would make it back in the motor because the material does not break into a fine dust ( that could cause oil consumpsion if sucked back into the motor.) like other kinds of catalyist material.

the sound is great their is no raspyness at all. it actually sounds like it has a small turbo ( you can just hear the air rushing through them ) without the wastegate. SHHHHHH
