Wagner Tuning Downpipe Catless BMW 1 Series (F20/F21) / 3 Series (F30/F31/F34)

Wagner Tuning Downpipe Catless - BMW 1 Series (F20/F21) / 3 Series (F30/F31/F34)

Wagner Tuning builds its exhaust hardware from CAD designed stainless steel, engineered to cut back pressure and reduce thermal load on the turbocharger. This catless downpipe is a direct replacement for the restrictive OEM unit on the BMW N20 platform, freeing up torque and power while keeping the factory fitment.

This listing covers the BMW 1 Series (F20/F21) and 3 Series (F30/F31/F34) fitted with the N20 engine from 10/2012 onwards. SKU 500001016. It replaces OEM part number 18327645666 and bolts in as a 100 percent direct fit.

Important: This is a catless downpipe — race and motorsport use only, not intended for road-registered vehicles. ECU tuning is strongly recommended to avoid check engine light issues once fitted.
