Thank you for the welcome. Today I tried another pipe on the bike with even better results although it looks more like i've fitted a baseball bat to it but the increase in torque is well worth it. the pipe was designed for a ZDZ 60cc model aircraft engine and the header section was obtained from another supplier called DL Engines. The header was cut up and reconfigured to the current shape the TIG welded back together by a friend of mine (thanks Greg).
There are many manufactures of these alloy 'Tuned Quiet' pipes that can be found on the web MAC'S and MTW are examples, the pipes I have are of unknown origin as they were obtained from a sidewalk sale.
