CTS Turbo downpipe for BMW N55 with electric wastegate

The CTS Turbo catalyst-free downpipe for BMW N55 with an electric wastegate is designed for the best possible exhaust gas flow and to replace the factory downpipe. It is made from T304 stainless steel, hand TIG-welded and welded with inert gas back-purging for long-term reliable operation.

The product was precisely designed using modern CAD technology and tested on a vehicle. It fits left-hand-drive vehicles; it is not suitable for right-hand-drive (RHD) vehicles.
