Like the title says. Started the car with open headers and when you give it a lil gas a ton of gray/black smoke comes out. Kinda hard to tell what color at night

Im hoping its normal. I have to check the plug wires again though. Its hard to get some of these MSD's to click

Some smoke is normal at first. Whenever you install new exhaust, the metal pipes have residue inside of them, which burns off. Basically it just needs to be broken in. You will also notice that it will smell funny for the first few miles as well, its normal.

If its still smoking after you have driven it for a while, then you might have an issue with something else.

Thanks guys. I let it sit for a bit and restarted it and it seems the smoke died down. If I didnt get out of that garage it would have seemed like I commited suicide with all those fumes. They did give me a instant headache...

you'll get fumes for sure and if they are coated... the coating has a break-in smoke until every settles in. and for the future... if you install hi flow cats, they will smoke and have a burning brake smell to them.

Mine did the exact same thing. A little smoke at first is normal. Give it a little time and the smoke should go away. Mine went away after just a mile or so. If it doesn't go away you may want to make sure you don't have other problems.

No smoke really, but the coating stunk for a couple hundred miles.

Went for a lil ride and it did smell like burning brakes.
