I have found a hole in one of my manifolds and have the option of paying $180 dollars for one (1) manifold from the dealer or putting a set of headers on. I have heard several negative comments about the headers leaking, etc. Any suggestions or comments will be helpful. I am considering Hedman headers. I've heard the headers should be welded to the "y-pipe". Is that true? What about putting on "shorty" headers? Thanks for the info. Chevy's RULE!
