Tecnigas GP4 Nickel Exhaust - Piaggio & Vespa 50cc 4T (2V)

Elevate your scooter's performance and style with the Tecnigas GP4 Exhaust System. Engineered specifically for Piaggio 50cc 4-stroke (2-valve) engines, the GP4 offers a "GP-style" aesthetic with a premium nickel-plated finish that resists corrosion and stays looking sharp long after standard painted pipes have faded.

This system is designed to provide a noticeable boost in mid-range torque and throttle response compared to the restrictive factory exhaust. Despite its sporty look, the GP4 is specifically baffled to remain quiet and neighbor-friendly, making it the perfect choice for daily commuters who want a lighter, more efficient setup without the high-decibel "drone" of a racing pipe.

Key Features:

• Corrosion Resistance: High-quality nickel plating provides a durable, mirror-like finish that won't rust.
• Weight Savings: Significantly lighter than the bulky OEM cast-iron exhaust for improved handling.
• Quiet Performance: Tuned for a deep, mellow tone that meets street-legal noise expectations.
• Complete Installation: Includes all necessary mounting brackets, hardware, and an instructional booklet.
