CKT Aero Engineering has been designing and fabricating exhaust systems for light aircraft and microlights since 1999.  Chris Piper, founder of CKT, was approached by the designer of the Europa light aircraft to design an exhaust system which suited the Rotax 912 engine and fitted within the Europa’s engine cowling.  The system had to be robust, lightweight, tolerate a wide temperature range, satisfy stringent noise regulations, with no impairment of engine performance and be easy to assemble by the aircraft’s kit-builder. 

Stainless steel was chosen as satisfying these requirements for the fabrication of the silencer, the tubing for the pipes leading from the four engine exhaust ports and for the exhaust exit pipe.  CKT uses EN 1.4301 (304) and EN 1.4948 (304H) steels working to QA standard ISO 9001:2008 and their welders are CAA (UK) approved. 

This standard silencer design with stainless steel pipe-work is the basis of design variants developed to suit more than 40 light aircraft models flying in many parts of the world.  There are now approaching 3000 CKT exhausts fitted to a wide range of light aircraft, microlights and Unmanned Aerial Vehicles (UAVs) some with over 2000 flying hours.
