Eisenmann Performance Exhaust - BMW F30/F31 320i / F32/F33/F36 420i (B48)

The Eisenmann 320i / 420i Performance Exhaust is a hand-built, T304 stainless steel exhaust system engineered specifically for BMW F30, F31, and F32/F33/F36 320i and 420i models equipped with the B48 four-cylinder engine. Developed in Germany using precision mandrel-bent tubing and hand-TIG-welded construction, this system delivers a refined performance exhaust note while maintaining factory-quality fitment.

Eisenmann has supplied OEM exhaust systems to Porsche and AMG for decades. That engineering heritage is reflected in the tolerances, finish quality, and sound character of every Eisenmann performance exhaust. Choose Sport for a noticeable tone improvement over the stock system without excessive drone at highway speeds, or Race for a more aggressive exhaust character. Note: center pipes are not compatible with automatic transmission or Sport automatic gearbox.
