After discovering a hole the size of a pencil in my #2 exhaust pipe going into the collector, jut before the merge with the #4 pipe, I received my new Power Flow Exhaust. Installation is straightforward and the only time consuming part is the cowling modification.

However, Roscoe’s video on converting to a short stack gave local A&P a great visual on how to implement the changes. Will be out of shop Monday, after touch up paint drys.
