Peter I like your new cowl, wonder if the Rotex 912 with exhaust will fit inside. My cowl is to small to fit a decent exhaust sistem. My 912 sound like a VW engin, becauce I could not fit a big enough silencer.
Russell did you make a mould of the new Jabiru cowl?
I see that there are no decent pics of the exhaust system on the blog...I will take some and add. In the interim here is a pic of the exhaust. There is a flex coupling and a silencer added to what you see here. The silencer hangs inside the tunnel.
