I just put new exhaust headers and cobra intake on car and i started it up. Smoke every where and a bad smell should it do that. Is it the gaskets burning on and stuff melting off exhaust. i shut it down when i seen the smoke and smeled the odder
The gaskets usually smell up and smoke.
Obviously they got hot, so i would retighten the bolts.
Then let it run.
As long as you don't have anything sitting on the headers you should be fine.
