Technical specification: outer diameter - 63,5 mm; wall thickness: 1,5 mm. The geometry supports free exhaust gas flow and reduces unnecessary restriction on the turbocharger side, making it suitable for performance-oriented exhaust systems. Sensor and port configuration: 1 port for lambda sensor. The layout supports installation of the specified lambda sensors, sensors and measuring ports, helping achieve clean integration into the exhaust system. Compatibility: Fits DECAT BMW E90,E91 M47N2; 318D,320D2004-2007; 122,163 PS. Check model, engine code, drivetrain, power level and production year against the vehicle data and VIN before ordering. Heavy-duty construction: stainless steel; wall thickness 1,5 mm; CNC machining / CNC cutting; Euro 3 catalytic core / catalytic converter. This combination is engineered for thermal durability, leak-tight connections and repeatable fitment in the high-temperature exhaust-side area. Performance-focused function: The downpipe is designed for reduced exhaust backpressure, quicker turbo spool and freer exhaust gas flow. This supports a sportier driving feel and stronger torque build-up in the low and mid RPM range. Features of this version: Euro 3 catalytic core / catalytic converter.
