.....On my ST90 I put a jett muffler............ I was after more torque rather than top speed........ The plane really sings on a 13X6APC now but is a little too fast, I was really looking for something to boost my performance on a 14X6. Those mufflers are pretty pricey too...........
the
Jett Stream muff is a tuned system for high RPM applications they aren't designed or intended for torque applications which is what you are/were after. the
Turbo Jett on the other hand is designed for more torque oriented applications.
as far as pricey goes, the Jett Stream is very cheap in comparison to a full length tuned pipe and only a few hundred RPM shy of it in performance, to most of use who are after all out speed we tend to conceder the Jett Stream very cheaply priced
