The Soul Performance Valved Exhaust System is a high-performance exhaust system designed specifically for the Porsche 911 GT4. It features a valved design that allows for both a sporty and aggressive sound when the valves are open, and a more refined and subtle tone when the valves are closed. The exhaust system is constructed from high-quality T304L stainless steel and features mandrel-bent piping for maximum flow and performance. It also includes a set of high-flow catalytic converters for improved exhaust flow and reduced back pressure. This exhaust system is designed to provide increased power, improved throttle response, and a more exhilarating driving experience for Porsche 911 GT4 owners.
