BMW M340i G20: Great Performance and Everyday Comfort

The BMW M340i G20 is part of the latest 3 Series saloon lineup, combining strong performance with everyday usability. Powered by a turbocharged 3.0 litre inline six engine producing up to 382 horsepower and 500 Nm of torque, it delivers smooth and responsive acceleration through the xDrive system and 8 speed automatic transmission. To enhance the driving experience, this vehicle received a custom BMW M340i Exhaust upgrade with a quad tip performance rear section, transforming both sound and flow.

Fast and Fuel Efficient

Capable of 0 to 62 mph in just 4.4 seconds and electronically limited to 155 mph, the M340i already offers impressive performance. The upgraded BMW M340i Exhaust System improves exhaust gas flow, helping the engine breathe more efficiently and sharpening throttle response. Alongside the exhaust work, the ECU was read and carefully adjusted to refine the engine calibration, ensuring the upgraded setup delivers smoother power and improved responsiveness.

Competing with the Best

In the UK’s premium sports saloon market, the G20 M340i competes with models such as the Audi S4, Mercedes AMG C43, and Alfa Romeo Giulia Quadrifoglio. With its upgraded quad tip exhaust system and tailored ECU adjustments, this example stands out with a deeper, more aggressive tone and a sharper, more engaging driving experience.

DKU Performance’s Customization Expertise

The focus of this upgrade was the custom built quad tip performance rear exhaust section. This setup enhances the rear styling with a more purposeful look while delivering a deeper and more refined exhaust note under load. The improved flow characteristics of the system combined with ECU calibration result in a more responsive and enjoyable drive, bringing out the full character of the M340i platform.
