They also come in ceramic coated but the recommended break in process was not friendly with a 30 mile drive home from the exhaust shop.

Thanks. I need center dump...I bit the bullet and ordered one exact reproduction (read expensive) manifold cast in the USA. I still have one original on the left side. So the cost of one exact reproduction is a little more than the two cheap china crap ones. I was thinking that I could have one as a spare. BUT I have to wait until mid January for the next batch. Sometimes it seems like nothing is easy.....
