Rotax and Hirth exhaust system update.

Another innovative idea from Stream Lined is an exhaust ball joint conversion kit. The kit which can be used on all Rotax, and Hirth two stroke  engines eliminates the springs and hooks, and replaces them with the more "conventional aircraft" style exhaust connection. 

This helps eliminate the problem of exhaust springs and hooks failing and going into your expensive propeller, possibly causing an emergency landing, and damage to your aircraft!

The kit which is constructed of stainless steel, with AN hardware is easy to install!

Note the pipes are NOT part of the kit - they are used here to show how the system mounts.

Hirth engines require 1
Rotax  2 stroke engines require 2 kits
Rotax 912 - 4 stroke require 1 for each pipe
