I just installed a 3" Doug's Dyno Power Downpipe, Testpipe, and Exhaust, and a 2G ported manifold. When I started my car back up smoke whitish smoke started to come out of the top of the new exhaust manifold. does anybody know what this is from?
 
It could just be residual stuff (oil, grease, fluid) burning off from the install. It should burn off after a few minutes of driving. If not, then you might have a leak somewhere...
 
ok, so no more smoke coming out of the manifold, but now the exhaust is producing a thin white smoke whenever the engine at any RPM's above idle. does this mean that i need to replace the head gasket?
