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. 


I just installed my steed speed manifold 4TI, works perfect with my stock VGT turbo. I purchased some exhaust bolts to dump the stubs and spacers. On cylinder 6 the bottom bolt I recommend the original stub spacer to hold the water pipe. Steed Speed will send you a backpressure adaptor for the little brake line that connect between cylinder 3 and 4. Perfect and more flow. This exhaust manifold rocks.

Very Well made very nice and worth the wait and perfect fit
