CTS Turbo B9 Audi RS5 High-Flow CATS

CTS Turbo's high-flow catalytic converters are precision-engineered for the B9 Audi RS5 twin-turbo V6 platform. These performance cats significantly reduce exhaust backpressure compared to factory units, allowing the turbos to spool more efficiently while maintaining emissions compliance. Direct bolt-on installation replaces restrictive OEM catalysts with larger substrate cores that flow substantially better. The result is improved throttle response, enhanced turbo efficiency and liberated power throughout the rev range. Built from stainless steel with durable high-temperature coatings, these cats are designed for tuned RS5 applications seeking measurable performance gains without compromising reliability.
