Audi A7 RS7 Rear Diffuser Conversion: A Sporty Upgrade
The Audi A7, even a decade after its debut, remains a benchmark for sleek and sporty design. For owners looking to enhance its already impressive aesthetics, converting to the more aggressive styling of the S7 or RS7 models is a popular choice. This review focuses on a specific upgrade: the RS7 rear diffuser conversion for an Audi A7 40 TFSI. The owner's vehicle had already received an RS7-style front-end conversion, making the rear diffuser upgrade essential for a cohesive and powerful look. This particular conversion utilized an all-black RS7 rear diffuser, aiming for a sophisticated and unified appearance.
Understanding the RS7 Rear Diffuser Upgrade
The primary motivation for this conversion is to imbue the A7's rear with the dynamic presence characteristic of the RS7. While the A7 boasts timeless elegance, the RS7 diffuser offers a lower, wider, and more performance-oriented stance. A key consideration before undertaking this body kit installation is ensuring compatibility. Audi A7 models, depending on their year and trim, can have subtle differences in bumper design, particularly around character lines and molding. Selecting the correct RS7 rear diffuser that offers a direct 1:1 fitment is crucial to avoid costly modifications or unsightly panel gaps. This specific installation involved a rear diffuser designed for later-model A7 vehicles, allowing for a straightforward replacement without extensive bodywork.
Installation Process: RS7 Rear Diffuser Conversion
The body kit installation for the RS7 rear diffuser on this Audi A7 involved two main stages:
- Exhaust Tip Modification: For the specific rear diffuser and the stock A7 exhaust configuration, the existing exhaust tips needed to be precisely cut and extended. This was necessary to align seamlessly with the wider, more aggressive outlets of the RS7 diffuser, ensuring proper exhaust flow and a clean aesthetic. This step requires skilled cutting and welding.
- RS7 Rear Diffuser Installation: Once the exhaust modifications were complete, the custom-ordered all-black RS7 rear diffuser was carefully fitted and secured to the A7's rear bumper. The focus during this stage is achieving a flush, gap-free fit, making the new diffuser appear as if it were a factory component.
The transformation is striking. The rear of the Audi A7 gains a significantly more aggressive and planted appearance. The all-black finish of the diffuser, including the exhaust outlets, adds a layer of premium sportiness. This body kit review highlights how such an aero kit upgrade can dramatically alter the car's perceived performance and style, effectively bridging the visual gap between the standard A7 and its high-performance RS7 counterpart. The estimated cost for this type of conversion in Korea, including parts and labor for the diffuser and exhaust modification, typically ranges from 500,000 to 1,000,000 KRW (approximately $375–$750 USD, though actual US body kit cost can vary significantly). The entire process usually takes about 3-4 hours, often completed within a single day.
