CTS Turbo B5 Audi A4 High Flow Cat

The CTS Turbo High Flow Cat is engineered specifically for B5 generation Audi A4 models from 1996 through 2001. This performance catalytic converter replaces the restrictive factory unit to significantly improve exhaust gas flow while maintaining emissions compliance. Built with a high-density substrate and quality stainless steel construction, it reduces backpressure throughout the rev range. The result is improved throttle response, better turbo spool characteristics, and a more aggressive exhaust note. Direct bolt-in fitment ensures straightforward installation with existing exhaust components.
