Wagner Tuning B58 Downpipe Catted BMW 340i (F30 LCI/F31 LCI) / M240i (F22)

Wagner Tuning B58 Downpipe Catted - BMW 340i (F30 LCI/F31 LCI) / M240i (F22)

Wagner Tuning builds its exhaust hardware in Germany with a strong background in turbocharging and B58 platform development, and this catted downpipe (SKU 500001027BMW) is designed as a direct replacement for the restrictive factory unit. It's engineered to cut back pressure while still running a high flow catalyst, giving the turbo an easier time and freeing up torque without going fully catless.

This listing covers the BMW 340i (F30 LCI/F31 LCI) and M240i (F22), both fitted with the B58 engine. The downpipe is a complete bolt in kit with an adapter section for the stock exhaust, so no cutting or permanent modification is needed to install it.

Note: Wagner Tuning recommends ECU tuning to properly extract the benefit of this downpipe. Running it on a stock tune is fine but gains will be limited until the car is retuned.
