Capristo Mid-Silencer Spare Pipes for the Mercedes-AMG ML63 (W164). These lightweight T309 (1.4828) Stainless Steel pipes are designed to replace the heavy OEM silencer assembly, removing the flow restriction and the resonator to deliver a more aggressive, unrestricted V8 biturbo exhaust note. Precision-bent and manually TIG-welded at our Sundern, Germany factory, these mid-silencer spare pipes are a direct fit for the Mercedes-Benz ML63 AMG W164 chassis when used in conjunction with the Capristo rear exhaust section. Eliminating the resonator reduces backpressure and allows the full character of the twin-turbocharged V8 to express itself.
