This is a lighter weight system than original made from 304 Stainless Steel. The system has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that sports car sound when required. The Active Valves are designed to perfectly replace the existing valve setup thus retaining all original functionality within the vehicle. With the valves open our system offers more depth throughout the rev range with pops and crackles on the over run and down change. When the Valves are then shut the system becomes much more civilised for a more discrete driving experience.
