A tuned exhaust system for small two cylinder engines, the exhaust system including
a pair of exhaust passage through which exhaust gasses pass. The exhaust passages
are dimensioned to providing a tuning effect to the exhaust gasses for enhanced
engine performance. The exhaust passages are not straight and elongated, but rather
are sprialed, scrolled, coiled, or otherwise folded upon themselves at least twice.
In this manner, the exhaust passages may be housed at least in part within a muffler
having a significantly reduced overall size or profile, such that the muffler may
be used in small engines.
