Please specify engine brand, size, and type (ex TT .40 Pro, OS .46FX, etc) when ordering

Note: Most modern ball bearing engines, both ringed and ABC type, have sleeve and porting designs that will take full advantage of the tuning effect created by the Jett-Stream muffler. Each engine design is slighly differnent, and therefore each type will show slighly different performance gains. Some will show more, some will show less than others.
