This is a discontinued item. We supply you substitute product with order number: 37320

Steel exhaust manifold, chrome-plated. Unobtrusive way to improve performance without having to invest in a new complete exhaust system. For most enduro geared mopeds with D50B0 engines, this exhaust is in two parts and has a two-piece end can which features a resonance pipe which strangles the engine power. Swap out for a version without this tube and the engine can breath and rev out. Less expensive than the stainless steel version.
