I just received my replacement RV-4 O-360 Vetterman 4-pipe exhaust today. I ordered it through Aircraft Spruce to replace the same system on my plane due to some metal wear from the heat muff and a crack in one of the pipes.
The problem I found when opening the box is that the new exhaust end/tip pieces are several inches shorter than what I am replacing (see the photo). The end/tip pieces on my prior setup are 11.5" long.
Does anyone know if those are an option from Vetterman or someone else? I tried calling Vetterman today, but haven't heard back yet. Thanks!
