Inconspicuous way to improve performance without having to invest in a completely new exhaust system. Most Piaggio models have exhausts that are divided into two and the manifold has a resonance tube which reduces the engine’s power. Changing this manifold for a version without this tube will release more power. A positive side effect is that it resembles the original.
