Tegiwa 4″ Catless Downpipe for the N55 engine as fitted to F2X M135i/M235i, F3X 335i/435i and F87 M2.

This stainless steel, TIG-welded downpipe are the perfect way to de-restrict the exhaust system of the N55 engine, allowing huge power potential and increased turbo spool. Also improves sound for a deeper, more purposeful exhaust note.

Please note that removal of emissions equipment is not MOT compliant and so these parts are for off-road use only.

Remap required to avoid check engine light. See Bootmod options here.
