CTS Turbo F2X/F3X 228i/328i/428i & xDrive N26 High-Flow CAT

CTS Turbo's high-flow catalytic converter is engineered specifically for F-series BMW N26 turbocharged four-cylinder applications. This performance catalyst reduces exhaust backpressure compared to the restrictive factory unit, allowing the turbocharger to spool more efficiently whilst maintaining proper emissions function. The precision-built housing integrates seamlessly into the OEM downpipe location on 228i, 328i, and 428i variants including xDrive models. Metal substrate construction ensures durability under increased heat cycles. Essential for workshops building comprehensive N26 exhaust systems where flow optimisation and compliance both matter.
