Burn-off smell from exhuast?

[Zane]

Anyone else noticing a strong burn-off chemical like smell from the exhaust every time you drive? It was quite strong the first few engine cycles and has gotten considerably better at 175 miles but is still noticeable when we get out of the truck.

Yes, mine had a very strong smell, gave me a slight headache at times. I'm coming up on 200 miles and it is way better now!

Yep me too.

 

It went away.

It’s a protective coating they put on the exhaust pipe when it is made to prevent rusting. 

 

It’s that plasticy feeling on new exhaust pipe.

uh yeah as a matter of fact, about 30 miles on mine and its pretty bad.

I could smell it till about 400 miles on mine.

I’m pretty sure yesterday was the first I’ve smelled it, almost 2k miles, pulling a trailer up a big hill.

They apply a oil inside the system when they install it to help break everything in.  It's the same as when you install a new flowmaster muffler.  They smell for the first 150-250 miles and then the smell goes away.
