Apexi has made the ultimate street exhaust system. It gives all-around performance, and is fine-tuned for low to mid-range power. To prove a point, Apexi performed numerous magazine dyno tests, and the World Sport 2 has proven to be the best one the market. WS2 doesn’t just provide great power, but also has a world-class sound that will keep you out of trouble. This system is perfect for daily driving without the loud noise associated with other exhaust systems.
