2003 W-22 Headers

Should I have the need to replace a exhaust manifold for a crack what would be a good product to consider? Stock manifolds are 1300$ if you can find one. All suggestions by current user of their suggestions would be helpful.

Yes Bank's Headers from Summit Racing. I ordered a set in the spring still have not installed them yet but looks like a weekend project, unless more problems with removing the old studs. Just have not had the time lately but can't wait to get them on. I must say they look like a quality set of headers and intermediate H Pipe so there should be no cutting of the old pipe just disconnect at the cat and install the new headers and pipe. I did order new O2 sensors from Rock Auto so no need to try to remove the old sensors. Good Luck

I went with Banks, I just ordered some, they just got some more in according to the guy at Banks I spoke with on Monday....

I am having exhaust issues and after reading many posts on here, this is the route I took.

Hopefully you can get the manifolds off without breaking any bolts. Mine had broken bolts before I started. I ended up taking it to a shop. $8000.00 later, I had headers installed. They tried to drill them out, but couldn't. They ended up pulling the heads. When they went to install the rebuilt heads, there ended up being an issue with the lifters. Several of them stuck. So the heads came back off, lifters replaced, and everything put back together. It was about worse case scenario.
