ok guys i put headman ceramic coated shorty headers on my car, no air injection, but i have this weird burning candle type smell i believe they are definately coming from the headers, i put about 400 miles on them, sometimes it smells worse than others, i checked all wires, and plug wires, nothing is melting, anyone else have this problem?

 

Check to see if the y-pipe is melting something.

 

nope the y-pipe isnt hitting anything

 

It doesn't have to hit something to melt it.

It could also just be grease/oil, etc. burning off. You know, the oil they ship it in and grease from handling them during installation. Although I wouldn't think there'd still be some after 400 miles. Did your car have AIR before the headers?

 

My headers have a few hundred miles on them and still have a burning smell also; it's the nature of the coating and protectant, I assume; it should go away after awhile.

 

i think its just hedman, mine were cheapies and they stunk for awhile too, pretty bad actually. but it got better after like 700 miles or so, didnt really keep track of the stink duration
