Other than the very simple Cummins riser, which really isn't a riser just an injection elbow that bolst up to the turbo, most risers are fabricated specifically to match the boat, layout and the height under the deck.

I know of a shop in NC and one in SoCal that can fabricate one for you. I am sure other forum members can recommend on nearer your location.

Where are you located?

What kind of boat is it and which way are you headed w/ the exhaust? I don't have anything, but the more info you provide the better someone might be able to help you. Six inch exhaust back of the riser?

Seaweags,

Start by reading these "exhaust design articles" by Tony Athens.
You might want to "give him a call" and ask if he has any "used" Cummins mixing elbows" kicking around his service/fabrication shop. You may get lucky.

The boat name is "Blitzen", I was anchored just behind the mooring field in front of the Sullivan house, about 500 feet downwind of you.
