exhaust manifold black unrestricted for Aprilia RS4 50 Euro4 2018- 39554
Unobtrusive way to increase performance without having to invest in a new complete exhaust system. On the most Enduro gearshift mopeds with D50B0 engine, the exhaust is divided into two parts and has a so-called resonance pipe at the manifold, which reduces the engine power. If the manifold is replaced with a version without this resonance tube, the engine continues to rotate and releases more power. Positive side effect: Looks like the original.
