Engineered exclusively for the B9.5 chassis, this diffuser is crafted from high-grade twill weave carbon fiber, paired with a precision-matched integrated tailpipe, and designed for gap-free installation that requires no modifications. It’s the top choice for B9.5 A5/S5 owners wanting to elevate their ride’s rear-end appeal with a professional, performance-focused transformation.

Key Features

✅ B9.5-Exclusive Fit for 2020-2024 A5/S5 Models
Precision-crafted for the 2020-2024 B9.5 platform, this premium carbon fiber rear diffuser is 100% compatible with all Audi A5 and S5 B9.5. Using 3D laser scanning of OEM B9.5 rear bumper data, it aligns flawlessly with factory contours, mounting points and exhaust positions — no gaps, no trimming, no forced adjustments. 
✅ Premium Twill Carbon Fiber Construction
Crafted from hand-laid twill weave carbon fiber with autoclave curing process, the diffuser delivers superior strength-to-weight ratio. The surface is finished with a 2-layer UV-stabilized gloss clear coat that resists fading, yellowing and oxidation, preserving a showroom-worthy shine for years. Unlike cheap carbon-look alternatives, this b9.5 s5 premium carbon fiber diffuser boasts authentic carbon fiber texture and motorsport-grade durability, withstanding road debris and extreme weather conditions.
✅ Integrated Tailpipe Design
Comes with a polished T-304 stainless steel integrated tailpipe that perfectly matches the diffuser’s exhaust cutouts — no need to source separate tailpipe components. The tailpipe features a slant-cut design with a mirror-polished finish, amplifying the B9.5’s sporty stance while ensuring smooth exhaust flow. This a5 b9.5 carbon fiber diffuser with integrated tailpipe creates a cohesive rear-end look that outperforms standalone diffusers or tailpipes.
✅ Seamless Fit Installation
Designed for true plug-and-play convenience, the diffuser uses factory mounting holes and hardware to achieve seamless fit that mirrors OEM components. Installation takes just 1-2 hours for professionals or experienced DIYers, requiring only standard auto tools — no drilling, cutting or welding is needed. The precision-engineered design preserves vehicle integrity and resale value, making it ideal for both leaseholders and modification enthusiasts.
✅ Sporty Upgrade - Aesthetics & Aerodynamics
Beyond visual enhancement, this diffuser delivers functional aerodynamic benefits: its angular fin design reduces rear airflow turbulence, improves downforce and enhances high-speed stability. The honeycomb mesh inserts replicate motorsport diffuser styling, adding aggressive depth to the B9.5’s rear end. It’s not just a cosmetic upgrade — it’s a sporty upgrade that elevates both appearance and performance.
