Great.

If you get the 26G pipe and try it on the engine, please report back on performance. We really liked the complete package the 40G results in (useful power output, sound quality/noise reduction, etc.) but isn't the only option. We simply don't have one to try

Important to understand that the baffle is set at 27 1/8" from the plug, straight line. At this setting, the engine was on pipe throughout the flight envelope. We still have some small mixture adjustments to make while the engine is breaking in, but that should give you guys a good, solid starting point. I wouldn't go any shorter than this length; 1/4" longer wouldn't hurt and may actually help a little
