Two-Stroke Exhaust DatabaseThis is a place to find a little bit of info about some two-stroke exhaust systems. I have gathered this information from manufacturer's websites as well as retailers and tuners. This is often general information, so I do suggest checking current specifications for your particular make/model or engine platform. Measurements and power figures could vary greatly from model to model and depending what was done to the engines tested. This is only a basic guideline and collection of info to give you an idea of where to begin to look. If you see pipes or specs that are missing or have additional info that you feel is useful, please PM me.

Yasuni Yasuni - Carrera 16 Classification : Sport/Race From Yasuni : "The Race 16 is the little brother of the Yasuni Race 21 exhaust system, with a bit less volume and a longer body. It stands out for its quality and exceptional details, including several reinforcements. It provides a fast terminal velocity and an ideal exhaust system for cylinders that work with a high number of revolutions."Yasuni - Carrera 20 RPM : 10,500 Classification : Race From Yasuni : "The Race 20 is a fully high-end exhaust system which must be combined with a competition cylinder of at least 70cc. The body of the Race 20 is a bit shorter than the Race 21, which provides it with more power in the mid range and slightly lower performance in the high range. As a result, the Race 20 does not reach such fast top speeds, but it is superior in terms of acceleration. Individual preferences must be taken into account when deciding between the Race 21 and the Race 20."Yasuni - Carrera 21 Classification : Race From Yasuni : "The Race 21 is a fully high-end exhaust system which must be combined with a competition cylinder of at least 70cc. The Race 21 delivers excellent results in the mid and high range, giving it a top speed somewhat superior to that of the Race 20. Individual preferences must be taken into account when deciding between the Race 21 and the Race 20."Yasuni - Carrera 30 Classification : Race From Yasuni : "The Race 30 is the pinnacle of the competition Race Range.
For perfectly modified engines (cylinders, starters and transmission), the Race 30's multiple cones, from the cylinder outlet itself to the silencer, reduce the overall weight and, above all, perfectly adjust the flow of gases for optimal cylinder filling-emptying. A true work of art to ensure the best results on the market."Yasuni - R RPM : 11,000RPM Classification : Sport / Race From Yasuni : "The “R” is the evolution of the "Z," with more volume and a wider cone, making it the ideal complement for 70cc Sport/MidRace cylinders. It works very well with 50 or 70cc cylinders, but its true efficiency becomes apparent with 70cc Sports cylinders. For superb performance, we recommend modifying the variator application. With certificate of approval."Yasuni - Z RPM : 10,500RPM Classification : Sport/Race From Yasuni : "The “Z” is a surprisingly powerful exhaust system that needs no other type of customisation. It also works with a 70cc cylinder. With certificate of approval." |
