Mounted Exhaust

Since I have the engine mounted, I decided to go ahead and mount the exhaust (mostly in an effort to get more boxes off of the floor that are taking up space.  First up, I needed to squeeze the rivets in the bottom center of the firewall where the cowl outlet sits (you can see the cowl at the bottom of the picture).  The outer portions of the bottom edge of the firewall will attach the lower edge of the cowl.

Here’s the cowl in place with all bolts torqued.  As I’ve mentioned before, I went with the Vetterman four pipe exhaust.

Here is what the exhaust looks like where it exits the cowl.  I like the look of this so much better than the crossover exhaust.  The only issue I ran into is that the four pipes stick out of the cowl slightly different amounts (over 1/2″ difference between the shortest and longest pipes).  I’ve emailed Larry Vetterman to see why this might be the case.

I went ahead and installed the oil filler neck and safety wired it to the case.

Checkoway had one of his hose clamps loosen in flight and recommended safety wiring them to prevent that.  Here, I’ve safety wired the intake tube hose clamps.

I also safety wired the hose clamps on the cylinder oil return lines.
