Description
Upgrade your BMW B46 engine with DCE Parts Performance Downpipes, designed to improve exhaust flow, reduce back pressure, and enhance turbocharger response. The larger-diameter downpipe allows the turbocharger to spool more efficiently, helping build boost at lower engine speeds and recover boost more quickly after gear changes.
When combined with the appropriate engine calibration, the DCE Parts Downpipe can contribute to improved performance, with typical gains of approximately 15 HP and 25 Nm of torque. The upgraded exhaust flow also produces a deeper, more aggressive exhaust sound while maintaining a performance-oriented appearance.
The DCE Parts B46 Downpipe is available with a High-Flow Catalytic Converter, including a 200-cell Sport Metallic Catalytic Converter configuration for applications where emissions equipment is required. ECU software optimization may be recommended to take full advantage of the improved exhaust flow and achieve optimal performance.
