Drained preservative oil from engine case and cylinders. Assembled and installed exhaust system. Found right side exhaust to be aimed slightly inboard but pointing toward the fuselage exhaust tunnel.
Left side exhaust is badly mis-manufactured. #6 exhaust almost touches the engine mount (0.088 inch clearance). #4 lower spark plug is blocked by #2 exhaust. Exhaust aims well inboard of fuselage exhaust tunnel.
Sent email with pictures to Performance Engines, supplier of exhaust system. Based on their record of non-response, I don't expect to hear from them anytime soon.
