Wagner Tuning Downpipe Catted - BMW 125i (F20/F21) / 320i/328i (F30/F31/F34)

Wagner Tuning is a German performance manufacturer known for precision engineered exhaust and turbo hardware built to OEM fitment standards. This catted downpipe is a direct replacement for the factory unit on the N20 engine, designed to cut back pressure and thermal load on the turbocharger while keeping a catalytic converter in place for a cleaner, more compliant upgrade. It bolts straight in for the BMW 125i F20/F21 and 320i/328i F30/F31/F34.

This listing covers the BMW 125i F20/F21, BMW 220i F22, BMW 320i F30/F31/F34, BMW 328i F30/F31/F34 and BMW 428i F32/F33/F36, all fitted with the N20 engine from 10/2012 onward. It replaces OEM part number 18327645666.

Note: ECU tuning is recommended after installation, as running without a retune may trigger a check engine light due to the reduced back pressure.
