      A few years ago, there were some videos of an Australian fellow who did it, showing how he did it.

        There are several ways to do this, for super pretty you have exhaust headers made with a 3-3 split. Discontinuing the heat riser will also discontinue the automatic choke, but that can be overcome with a manual choke. Without the heat riser there will be a longer warm up time with limited response from the throttle when cold, this can be over come with a block heater. I did a backyard job by drilling a hole in the manifold and adding a pipe it was not a clean 3-3 split but it had a very different sound (I was 17 at the time) It is a lot of work and time for very little gain but it was fun to do at 17.

          The Aussie that posted the videos is a friend of mine. I just emailed him and asked him to re-post them in this thread.

                  Go to You Tube and look up " 1951 Studebaker revamp" . I could not get the direct link to copy.
