Dinan Valved Axle-Back Exhaust System with Polished Tips for BMW 330i / 430i 2019-2024

The Dinan Free Flow Axle-Back Exhaust for the BMW G20 330i / G22 430i enhances both performance and sound without compromise. Designed specifically for the B46/B48 4-cylinder turbocharged engine, this exhaust system offers improved exhaust flow by reducing backpressure while delivering a deeper, fuller sound. It strikes a balance between performance gains and refined sound quality, with no added drone or other negative side effects common to aftermarket exhaust systems.

Key Features:

• Performance Gains:

  • +4 HP and +3 ft-lb of torque at maximum gains, improving overall power and responsiveness.

• Enhanced Sound:

  • Enjoy a louder, sportier sound that makes driving more enjoyable, yet remains civil with the factory valve control for quieter operation when desired.
  • Drone abatement technologies are implemented to reduce unwanted cabin resonance, ensuring a comfortable experience even during long drives.

• Larger Exhaust Tips:

  • The dual 4" (102mm) double-walled, polished clamp-on exhaust tips with the laser-engraved Dinan logo give the car a more aggressive and high-performance appearance, especially when compared to the stock 90mm (3.5") tips.

• Improved Flow:

  • The exhaust system uses larger diameter piping (85mm to dual 60mm vs. 85mm to dual 83mm in the stock exhaust) to maximize airflow, improving the engine's efficiency and responsiveness.

• Durable Construction:

  • Made from 100% T304 stainless steel and TIG welded for durability and corrosion resistance, the Dinan exhaust system is built to last and maintain its performance over time.

• Factory Valve Control Retained:

  • For quieter operation, the system retains the factory valve control, allowing you to adjust the exhaust tone depending on driving conditions. This feature is ideal for those who need a more subdued sound in certain situations, like early morning or late-night driving.

• OEM-Like Fitment:

  • The system is designed for a factory-like fitment, using factory cut points and mounting mechanics, making installation straightforward and ensuring precision fitment without modifications. All necessary mounting hardware is included.
