Gang,

I'm looking into the option of ceramic coating my long tube kooks (with cats & x-pipe) before I install them.

In searching for local shops that can do the coating, I encountered a couple random posts where people warned that ceramic coated headers would destroy the catalytic converters.

Is it true that ceramic coated headers and cats are a no-no together?

Any feedback is most appreciated...

thx,

I've never heard that and both of my cars have ceramic coated headers and cats.

that is stupid. thousands of cars out there. call any of the major coating shops. i have never had a problem neither has anyone i have ever talked to. ask vendors who offer coated exhaust with cats if it messed up cats they wouldnt sell coated headers with catted systems.

Nope..coating the cats is fine..though I don't really recommend it since there is no performance gain.

I destroyed two sets of cats. I'm running LG Pro LTs that are ceramic coated. A&A found the first one (Both cats) when doing a SC upgrade. They replaced them and the replacements went as well. I can't say the coated headers were the cause. I put the blanks in and never figured out what the cause was.

Normally cats will fail because of an incorrect engine calibration that is too lean or too rich. A tuner will never admit this, but you normally can tell by looking at the cats what the cause was.
