CTS Turbo 3″ Stainless Steel Highflow Cats BMW S55 F80 F82 F87 M3/M4/M2 Competition

CTS Turbo's 3-inch stainless steel high flow catalytic converters are engineered specifically for the S55-powered BMW M3 F80, M4 F82/F83, and M2 Competition F87. These performance-oriented cats reduce exhaust restriction while maintaining catalytic function, enabling improved throttle response and a more aggressive exhaust note. Constructed from durable stainless steel, they're designed as a direct replacement for the factory units. The larger 3-inch diameter core optimises flow characteristics throughout the rev range, making them an ideal foundation for comprehensive exhaust system upgrades or standalone performance enhancement.
