Did you have the cat before you install the header? if you did then it might be the issue.

Did it come with any gaskets? And if so did you install them?

i had one cat from the header but that went away went i instaled the aftermarket headers.

and yes i took the donut gasket from the old header and put it on the new one. should it be tightened?

Not sure what you mean by should it be tightened?

There was no gasket between the head and header?

The smell is from running no cats on the vehicle, nothing else is wrong with the car.

what are you smelling exactly... free flow exhaust, means more fumes out. cat are built to absorb some chemicals and just let less harmful ones pass. so you should be fine... just make sure you are not smoking. white fume usually means water, black - gas and bluish oil...

yes i have a gasget from the head to header, and its probably because i have no cats

man you should be expecting that when you go catless!!! that's why the cat is required in all states.

Gasket wouldn't make a difference for exhaust smell, if you read the people in the thread that helped you'd see it's because you have no cats.

New gaskets as opposed to reusing the old ones would help if the smell is coming from a leak somewhere, but the smell is normal for a catless exhaust.

If there was a leak it would be ungodly loud.

also check for the leaks via sound, when u rev it up, if it sounds farty and raspy from the FRONT of the car, better get that plugged up! =) I had that issue. Rasp from the rear end, better put on some resonator (s)
