Wagner Tuning Downpipe Kit Catless - BMW 135i (E82/E88) / 335i (E90/E91/E92/E93)
Wagner Tuning builds its exhaust hardware in Germany from stainless steel 1.4301 (SS304), engineering downpipes that reduce back pressure and thermal load on the turbocharger while keeping a true OEM-style fit. This catless downpipe kit is designed as a direct replacement for the BMW 135i and 335i N55 platforms, freeing up torque and airflow that the factory catalytic converter restricts. SKU 500001015.
This listing covers the BMW 135i (E82/E88) and BMW 335i (E90/E91/E92/E93), both fitted with the N55 turbocharged engine. The kit is a bolt in replacement for the OEM downpipe section, retaining factory mounting points for a straightforward install.
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 prevent engine management light errors once the catalytic converter is removed.
