Wagner Tuning BMW F-series B58 Downpipe Catless- 500001027BMW-CL

Wagner Tuning B58 Catless Downpipe - BMW 1/2/3/4 Series (F20/F22/F30 LCI/F31 LCI/F32/F32 LCI)

Wagner Tuning builds its exhaust hardware from motorsport grade stainless steel, and this catless downpipe (SKU 500001027BMW-CL) is designed to unlock the full potential of the B58 engine fitted across BMW's F-series line up. It replaces the restrictive factory downpipe with a free flowing 89mm (3.5 in) section, cutting back pressure and easing thermal load on the turbocharger for stronger mid range torque and quicker spool.

This listing covers the BMW M140i (F20), M240i (F22), 340i (F30 LCI/F31 LCI), 440i (F32/F32 LCI) and 540i fitted with the B58 engine.

Important: this is a catless downpipe — race and motorsport use only, not intended for road registered vehicles. Removing the catalytic converter will trigger a check engine light, and Wagner Tuning recommends ECU tuning to properly manage the change in exhaust flow.
