CAP 3.0T Resonated Midpipes for 2018–2024 Audi B9/B9.5 S4 & S5

CAP 3.0T B9/B9.5 S4/S5 Resonated Midpipes With Direct Fit

Refined Sound, Zero Compromise Between Comfort and Performance

Canadian Auto Performance (CAP) proudly introduces our Resonated Midpipes for the B9 platform—engineered for enthusiasts who want added performance without sacrificing daily drivability.

Take your Audi B9/B9.5 S4 or S5 to the next level with CAP Resonated Midpipes—a premium solution for those seeking smoother tone, reduced cabin drone, and enhanced exhaust flow without going full straight-pipe.

These midpipes replace the factory resonated mid-section with a refined 2.5” mandrel-bent 304 stainless steel design, featuring a pair of high-quality resonators that reduce harshness while preserving the rich, aggressive tone Audi owners love. A heatshielded flex pipe section is integrated that helps retain heat within the piping which promotes better exhaust flow and allowing your engine to run more efficiently while also contributing to the long-term health and longevity of the engine. Compared to the stock 2.25” piping, expect improved airflow and a more enjoyable driving experience across all RPM ranges.

Designed to fit after the downpipe, these midpipes bolts up cleanly to:

• OEM Downpipe
• CAP Downpipe
• Other branded Downpipes

Important Note: These midpipes will NOT trigger a CEL, as they retain all factory catalytic converters.

Experience a refined exhaust note, improved turbo efficiency, and measurable power gains—all while maintaining everyday comfort.
