The CTS Turbo 4″ high-flow catalyst for BMW N55 with an electronic wastegate is designed for the best possible exhaust gas flow. It replaces the factory downpipe and enables more efficient exhaust system flow.
The product was designed using modern CAD technology, ensuring an exact fit in the factory downpipe position. It is made from T304 stainless steel, hand TIG-welded and welded with internal protection for long-term reliable operation.
Features

Suitable software calibration is required to eliminate the engine warning light (CEL), which may appear after installation. Using a Bootmod3 downpipe software upgrade is recommended. The product is intended exclusively for use off public roads and is not road-legal in the EU.
The product does not fit right-hand-drive vehicles. It is suitable for BMW N55 engines with an electronic wastegate and the listed vehicle versions in the compatibility table.
Stage 2 software is required to prevent the engine warning light.
