exhaust manifold TECNO Aprilia SR 50 LC 00-04 unrestricted [ZD4RL0/RLA/RLB/RLC/RLE/TP]

An inconspicuous way to improve performance without investing in a completely new exhaust system. Most Piaggio models have exhausts divided into two parts, and the manifold has a resonance tube that reduces engine power. Replacing this manifold with a version without the tube will release more power. A positive side effect is that it resembles the original.
