CTS Turbo high-flow catalytic converters for BMW S58 are designed as part of a modular exhaust system and are compatible with factory centre pipes. The stainless steel pipes enable faster turbocharger response, improved response to changes in boost pressure, higher boost pressure and a more pronounced sound.<\/p>\n

Exhaust gas flow was optimised using CAD simulation, ensuring correct flow direction and compatibility with factory and CTS Turbo exhaust components. When used with suitable engine tuning software, a significant improvement in torque can be expected.<\/p>\n

Bootmod3 software is compatible and its use is strongly recommended. If suitable software tuning is not used, the check engine light (CEL) will come on.<\/strong><\/p>\n

Two new BMW 18308053348 gaskets are required and are not included.<\/strong><\/p>\n
