I ordered a set of Dynomax Cerama-coat headers and am wondering if I need to either drill a hole for the O2 sensor or if I need a different set of headers. I have a stock LG4 with a comp-controlled QJet.

Thanks,
Matt

 

if you need o2 sensor then you need to weld the little bung in place. they sell them in summit for like 12 bucks. you will have to grind them to weld in the bung so you will ruin the coating. you could put a heated 02 sensor in the Y pipe that way the headers stay coated. or you could get a set of headers with the o2 sensor fitting in them. last option is to grind and weld then send them and have them re-coated.

Do you know where I can get a heated O2 sensor?

Check the footnotes on their web site. If you ordered the ones for your car, they usually come with a bung for the O2 sensor.
