It's normal, just give it awhile and it'll go away since it's all new pipping.

When I first started my car after the swap, the header smelled like rotten football socks, and smoked too.

My dad just grinned and said, "It's normal".

could be the gaskets wearing in too. mine never really smelled, but ever since i got the straight thru i can smell gas much more in the morning (cuz the flow is much better now, so the unburned fuel doesnt stick in the stock muffler).

Company's use a lubricant to bend pipeing. When you install a muffler you usually never smell it because nothing is bent but when you install anything with bent pipeing it will have an odd smell and sometimes blow out a little bit of white smoke....Headers are the same way. Actually there are 2 types of lube that are used.....One for welding and one for mandrel bending.....Even if it is done precision on a robotic welder/bender the machine will use the lube as well

I worked at a muffler shop for about a year before I joined the Air Force. We did our own bending for custom exhaust. We had to mandrel machines at the shop. They are very expensive.I never did any welding. My job was to fit, measure, bend, refit to exact specs of stock exhaust.....People dont really think about this but car companys usually have the exhaust routed in the best location and usually have the least amount of bends for max performance but......hahahahahah......they use the most restrictive piping in the world

When we did my 95 Accord (the first car I ever did my own exhaust on)...the stock piping was like 1.5 inch....it was absolutely horrible....That explains alot about why Japanese car respond so well to boltons......They build the awesome engines and then they restrict the hell out of it with stuff like that

Yup - normal

My dynomax smelled on my old SXT

And my Flowmaster smelled on my Jeep Cherokee

- Youll get similar smells if you run a brand new car very hard as well
