Is it common for brand new headders to smoke? I don't have the exhaust hooked up yet but there is smoke intermittently coming from both headers, a strong burning smell not like combustion. The headders definately aren't touching anything. It never does this at idle sometimes when I give it gas. Thanks!

 

If their painted headers then its just the paint burning...

 

Quick question if you don't mind.....

Mines doing this too (Hooker 2460's) how long will it take to stop smoking?

 

Usually goes away after a few minutes in my experience.

 

I haven't actually driven it yet with them on, but had it running in the driveway for about 10 min. & they were still smoking away. But was just wondering.

 

Mine longtubes smoked during the whole cam breakin. Went away shortly after that.

 

Yea, give it a few days. That paint will burn off, and you'll want to paint them with some real high temp paint. If it is high temp paint, then it's just curing.
If you can't see any plastic or anything burning, you're ok. And yea, it smells just god-awful.

 

It might be grease and grit from your hands while installation.
