<p>A tuned exhaust system for small two cylinder engines, the exhaust system including an exhaust passage (100) 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 (130, 170, 180) having a significantly reduced overall size or profile, such that the muffler may be used in small engines. <IMAGE>A tuned exhaust system for small two cylinder engines, the exhaust system including an exhaust passage (100) through which exhaust gasses pass.
