They have a narrow tuning band for were they will and will not perform...

IF those are K-82's or 67.... go with tried and tested mac 13 or 11 cc pipes with mufflers...can't miss.

A couple things on the Cooper pipes, if you are running big props, with a lot of pitch, set the pipe length @ 11 1/2 measured from the center of the engine side to the center of the the big band.smaller props and smaller pitch, shorten the pipes 1/4 inch and try it, may go all the way down to 10 1/2 inches for more RPM, I ran 1 third channel on the inside engine and a manual meter on the outside engine. It is easy to bring the third channel engine in RPM in sync to the out side engine.
