Ceramic coated headers safe with Cat?
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,
ando

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.

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.
