Lextek Stainless Steel YP4 Full Exhaust System for Lexmoto Echo 50 (17-24) by Lextek.
Motorcycle exhaust pipes are fitted with silencers at the end to reduce the noise from the engine. The silencer attached at the end of the exhaust pipes causes the gases to expand so that any noise is expelled. The linings and perforations in the silencer also help lower the volume of the engine.
