Exhaust manifold -101 OCTANE- unrestricted – for Aprilia RS4 50 Euro4 – black svendita

Unobtrusive way to increase performance without having to invest in a new complete exhaust system. On most enduro shift mopeds with D50B0 engine, the exhaust is split in two and has a so-called resonance pipe on the manifold, which reduces the engine power. If you now replace the manifold with a version without this resonance tube, the engine turns out further and releases more power. Positive side effect: Looks like original.
