well i had to geind out the id of the 4" side to fit over the turbo down pipe. if they would have welded the 4"flange to the end of the adapter pipe in the middle it would have been a perfect fit but they flushed the inner pipe to the outside edge. no idea what they were trying to acomplish there. quality is good and measurements were accurate to thw point of modifications required. for the price it was good but thw labor and cost of grinding wheels i could have just ordered a $100 part. used on 2006 dodge cummins turbo as down pipe adapter. no v-bamds included after i finally finished extremem mods and installed the part. back to the part store for and extra v-band clamp.
