Just to close out this thread, I took Chryco's PVC idea and modified it slightly. I went to the washer/dryer section of Lowes this morning and found a great and CHEAP solution to vent exhaust on a T/A tip so you can work on it in your garage without begin gassed out. The metal piece that goes over the tip is a 4" configurable piece of light gauge metal. By turning the pieces in a given direction you can configure the metal from 0-90 degree angle. Then I just screw clamped on an 8' metallic dryer vent hose, and presto - instant vent! I put a cinder block up against it so that it doesnt blow off on rev. This was only $33 in parts from Lowes, as opposed to the $200 set I was looking at on summit.
