This is a lighter weight system than original made from 304 Stainless Steel tubing and a smaller Titanium Ultralight silencer casing . The system has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that sports car sound w ith more grumble, pops and crackles on the overrun. 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 and a fantastic sporty sound. When the Valves are then shut the system becomes much more civilised for a more discrete driving experience, perfect for early starts and long journeys.
