Hi,

Thank you for writing....

A number of Jett pilots fly with the exhaust diverter tubes. However, you want to make sure you have the larger one, with an inside diameter that is larger than the exhaust outlet.

If the ID is too small, or if you have a kink in the tube, you will restrict the exhaust and cause the engine to run poorly.

Typically installation of a silicone type extension tube is simple.

1) clean the tailcone of the muffler with alcohol. Let dry

2) clean the diverter with alcohol

2) apply a thin film of high temperature RTV silicone. You only need a small amount.

3) Install the exhaust diverter. Use the cable tie to secure it in place.

Allow this to cure/dry for at least 24 hours.

When done, it should remain secure.

Attached is a photo of such an installation. A good number of flights on this particualar aircraft.


I trust this is helpful.
