This month's Diesel Power has an article (page 122) on the installation of the 3 Piece ATS Manifold - which I think is great - what amased me was that they found a drop of about 100 degrees in EGT - I didn't realize that was possible... ... also the performance seemed better - I have my own thoughts - what appears to be yours..... actual experience would be beneficial - not wanting to spend $600 for something that I'm notsure of... ... . and my manifold is not cracked at this point.....
