This manifold is built with an Exhaust Flange designed to fit the STOCK VGT turbo found on 07.5-18 6.7L Cummins diesels. Some people call it a T4I flange.. It probably won't fit any other style turbo unless the flange is identical to the turbos found on the 07.5-18 trucks.
Your satisfaction is guaranteed! If for any reason you are not happy with your Cummins manifold you can return it to us for a full refund.
**Does NOT come with any manifold to cylinder head mounting hardware**
