CTS Turbo 3" Stainless Steel High-Flow 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 BMW S55 engine in F80 M3, F82 M4 and F87 M2 Competition models. These cats replace the restrictive factory units with larger-diameter 200-cell metallic substrate cores that significantly reduce backpressure throughout the rev range. The result is improved throttle response, enhanced exhaust note and optimised flow to complement upgraded turbo systems or downpipes. Constructed from T304 stainless steel with precision CNC-machined flanges, they're built to withstand high exhaust gas temperatures while maintaining long-term durability in Australian conditions.
