Details

• Built for Performance.
• While many aftermarket exhaust systems for the Audi B8/B8.5 S4 deliver impressive sound when paired with factory catalytic converters, a common issue arises as those OEM cats begin to fail—often due to heat-related breakdown over time.
• As a result, many owners turn to catless test pipes, which unfortunately introduce excessive rasp, harshness, and unwanted exhaust tones when combined with most existing exhaust systems.
• As the global leader in test pipe sales for the B8/B8.5 S4 3.0T , CAP recognized the need for a purpose-built solution for vehicles equipped with catless test pipes.
• Since 2020 , our team has been developing an exhaust system specifically engineered to work in harmony with catless test pipes .
• The focus was on eliminating unpleasant high-frequency tones and resonance, while maintaining optimal flow and performance.
• The result is a cat-back exhaust system that delivers a deep, aggressive, and refined sound —even without catalytic converters.
• Real-world tested on over a dozen vehicles across varied driving conditions, this system reflects over four years of product development and refinement.
• For enthusiasts running catless setups, this is the most acoustically balanced and performance-driven exhaust solution available for the Audi B8/B8.5 S4 3.0T.
