Howdy guys. These engines have been around forever so I'm sure plenty of people have experience with the exhaust manifolds. Mine is cracked dead in the center where the turbo mounts. Is it worth the money to get a high performance or one piece manifold? In the past I never bothered but I am considering one this time around. I thought the new ceramic coatings you can get alone might be worth it. Supposedly helps with flow exhaust temps. Or is it all a waste of time and I should just get a $400 dollar no name one? Let me know your experience! Thanks.
