CTS Turbo BMW S58 F97/G01 X3M/X3MC & F98/G02 X4M/X4MC High-Flow CATS

CTS Turbo's high-flow catalytic converters are engineered specifically for the BMW S58-powered X3M and X4M models across G01 and G02 platforms. These performance cats address the restrictive factory catalysts that limit exhaust flow on the twin-turbo straight-six. The design reduces backpressure through the turbocharged system while maintaining necessary emissions function. Direct bolt-in replacement for both standard and Competition variants from 2019 onwards. Essential for tuners building complete exhaust systems where factory catalysts create a bottleneck in the performance equation.
