With fewer flow restrictions and a more efficient crossover, the engine can evacuate exhaust gases more easily. This is especially valuable on tuned or higher-boost S58 cars, where the factory exhaust becomes a larger part of the overall flow limitation. The ERGE design is intended to support stronger response and more consistent power delivery without turning the car into an excessively loud straight-pipe setup.\u003c\/p\u003e\n\u003c\/section\u003e\n\n\u003csection style=\"margin:0 0 30px\"\u003e\n\u003cp style=\"font-size:20px;font-weight:700;line-height:1.35;color:#202124;margin:0 0 12px\"\u003eSound character\u003c\/p\u003e\n\u003cp style=\"font-size:14px;line-height:1.85;color:#565b61;margin:0\"\u003eThis is not designed simply to make the car louder. The 3D-printed crossover changes how the two banks interact, giving the S58 a fuller and more coherent exhaust note.
