The CTS Turbo high-flow catalytic converter for BMW N26 is designed to improve exhaust gas flow and increase performance potential. It replaces the factory downpipe with a high-flow version that improves flow and provides a sportier exhaust sound.
The product was designed using modern CAD technology, so it installs in place of the original downpipe. It is made from T304 stainless steel, TIG-welded and internally back-purged during welding, ensuring long-lasting reliable operation.
