46PRO & 52PRO - Muffler Distance from Engine - How to Increase It?
Question: My aircraft has a tapered nose the flairs out quite broadly around and aft of the firewall. When I try to install my muffler on the engine the exhaust nozzle end of the muffler contacts the fuselage and I cannot tighten the muffler firmly to the engine. What can I do about this?
 
Answer: The easiest solution to try first is to install a spacer between the engine exhaust stack and the intake of the muffler. We offer a 10mm spacer specifically for the VMAX 46PRO & 52PRO. This is part number VXR-46400010. We recommend only using one such spacer. Ganging spacers up will increase the space but runs the risk of inducing vibration and extra torque on the engine exhaust stack which can damage the engine crankcase.
