While originally it was discussed to direct the exhaust straight out the hood. I changed my mind and decided to utilize a full-exhaust system. The first job was to fabricate a downpipe to direct the hot exhaust under the cab, instead of out the hood.
The shop who installed the hot side, provided me with a downpipe from another project which was not being utilized. I used this piece of scrap tubing as the starting point for my downpipe.
