I just purchased the DC sports header for my 2006 pontiac vibe. I am unsure as to weather when I do install if I will need any gaskets or new bolts since the new header didn't come with any. Any help would be greatly appreciated!

1. Whether
2. You can reuse the manifold gasket at the block, but you're best to get a new donut gasket for the midpipe side

manifold gaskets are cheap, just get a new one.  

 

Thing was a beyatch to install (have a scar on my hand from removing the existing manifold from the brace on the underside of it).  Good luck, it can be a diy, but a pain.

Should I be expecting the donut gasket at the converter to be welded on?

Not necessarily, but can expect it to be a bit tattered. I find it easier drop the manifold with the passenger axle out of the way and drop the manifolds out of the bottom. If you need bolts, they're pretty cheap through Toyota, or at least they are through my local dealer: Jimwhitetoyota.com

I've only ever brought the manifold out the top.  The O2 sensor will be extremely tight, even more so if your classmate crossthreads it back in.

 

The donut shouldn't be stuck.  Try not to damage it.  It should be reusable, as it can reshape a little bit to reseal from what I can tell. (removed mine 3 or 4 times with no issue).

 

I think you can re-use the steel one unless you accidentally split up the layers, but I'm not going to recommend it because it doesn't seem to reseal as well.  A flat graphite gasket, however, will almost always fall apart if you remove it in my experience.


...Did you try hitting it with a hammer?

Don't reuse the donut gasket.  Ever.  Unless it's damn near brand new.

 

It isn't welded on; you can't weld them.  It may appear that way though based on how badly it gets stuck.  But if you buy a new one, it doesn't matter; just leave it attached to the old exhaust manifold.

 

And as others have said, exhaust gaskets are cheap (like $12).  Just buy a new one.
