Wagner Tuning BMW F-series N55 7/2013 Downpipe Catless 500001017

Wagner Tuning BMW F-series N55 Downpipe Catless

Wagner Tuning builds this catless downpipe (SKU 500001017) from CAD-designed 1.4301 (SS304) stainless steel, engineered as a high flow decat replacement for the restrictive OEM unit on the N55 powered BMW F-series. Removing the factory catalytic converter cuts back pressure and thermal load on the turbocharger, freeing up torque and power delivery.

This listing covers the BMW M135i(x) and M135i F20 / F21 (07/2013 onward), BMW M235i(x) F22, BMW M2 F87, BMW 335i(x) F30 / F31 / F34 (07/2013 onward), and BMW 435i(x) F32 / F33 (07/2013 onward). It replaces OEM part number 18328602882 and bolts straight into the factory location.

Important: This downpipe is catless and intended for race and motorsport use only — not intended for road-registered vehicles. The ECU will need to be coded to avoid engine management light errors after fitment.
