Upgrade the exhaust character and performance of your compatible BMW with the Dinan D660-0046-BLK Free Flow Axle-Back Exhaust. Designed for 2012-2015 BMW 328i and 428i models on the F30, F31, F32, and F33 platforms, this stainless steel exhaust system improves exhaust flow by reducing back pressure. The result is a sportier exhaust note and measured gains of up to 4 horsepower and 3 lb-ft of torque at 6,600 RPM, while maintaining a refined driving experience for daily use.
The Dinan axle-back exhaust features twin 2.75-inch laser-engraved black exhaust tips for a clean, performance-focused appearance. It uses the vehicle’s factory brackets and hangers to provide a factory-like fitment and straightforward installation. Constructed from durable 304 stainless steel, the system is engineered for long-term corrosion resistance and dependable performance under demanding conditions.
Dinan incorporates drone abatement technology to help reduce low-RPM cabin resonance. This allows the exhaust to deliver a louder, more aggressive sound during acceleration without overwhelming the interior during cruising. The Free Flow Axle-Back Exhaust is a practical choice for BMW owners seeking improved sound, enhanced airflow, and a subtle visual upgrade without sacrificing everyday comfort.
Designed for select 2012-2015 BMW 328i, 328i xDrive, 428i, and 428i xDrive applications, the Dinan D660-0046-BLK combines proven engineering with high-quality materials. Verify vehicle fitment before installation, as compatibility varies by model year, body style, and drivetrain.
