Exhaust tunnel clearance

[wingnut99]

Has anyone had problems getting their generation 4 Jabiru 3300 exhaust pipes to clear the front of the exhaust tunnels? Mine were barely clearing until I installed the cooling baffles and now I have to work the cowling inlets into the baffling flanges as I'm raising the rear of the lower cowl into place and the exhaust pipes, especially the passenger side is hitting the top of the aluminum tunnel about a 1 1/2" behind the front of the tunnel. I can do surgery on the tunnels if that's what's required but I could have located them further back on the cowl had I known ahead of time.
