2019–2021 Audi A7 S-Line / S7 4KA Sportback Rear Bumper Diffuser Lip with Tailpipe Outlets – Dry Carbon Fiber

2019–2021 Audi A7 S-Line / S7 4KA Sportback Rear Bumper Diffuser Lip with Tailpipe Outlets – Dry Carbon Fiber

Transform the rear profile of your Audi A7 S-Line or S7 Sportback with this dry carbon fiber rear bumper diffuser lip with integrated tailpipe outlets. Supplied as a handed two-piece set and molded for the factory rear bumper, it sharpens the lower rear end — visually lowering and widening the rear stance for a more aggressive, motorsport-inspired presence with a genuine dry carbon finish.

Build

• Material: Genuine dry carbon fiber, autoclave cured using a 3D design and CNC moulding process for a tighter, more consistent weave and a superior strength-to-weight ratio compared to standard wet carbon or carbon-look alternatives
• Surface finish: High-gloss epoxy-polished top coat that holds its deep dry carbon appearance through sustained outdoor and driving exposure without fading or yellowing
• Configuration: Handed two-piece set with integrated tailpipe outlets for coverage across the lower rear bumper
• Weight: Lightweight at approximately 1.14 kg for the complete set

Design & Aerodynamics

• Aggressive stance: Diffuser lip profile visually lowers and widens the rear stance for a more track-inspired rear-end presence
• Integrated tailpipe outlets: Shaped to frame the exhaust tips for a coordinated, factory-integrated look at the lower rear bumper
• Carbon aesthetic: Refined dry carbon weave and gloss finish complement the factory Sportback bodywork for a coordinated, motorsport-grade look

Fitment

• 2019–2021 Audi A7 Sportback S-Line (4KA)
• 2019–2021 Audi S7 Sportback (4KA)
• Fits A7 S-Line and S7 factory rear bumper only — not compatible with the standard non-S-Line A7 or aftermarket bumper configurations
• Body style: Sportback (4-door) only

Package Contents

• 2 × dry carbon fiber rear bumper diffuser lip pieces with tailpipe outlets (left and right)
• Pre-applied adhesive tape for installation

Installation

• No-drill, adhesive-mounted: Installs with the included adhesive tape — no drilling and no permanent modification to the factory rear bumper
• Surface prep: Thoroughly clean, degrease, and dry the rear bumper at each mounting position before fitting to ensure maximum adhesion
• Check orientation and outlet alignment: The pieces are handed — confirm correct left and right sides, and verify the tailpipe outlets line up with your exhaust tip positioning before final adhesion
• Professional installation recommended for the best positioning, symmetrical alignment, and finish

Before You Install

• Confirm your car is an A7 S-Line or S7 Sportback (2019–2021) before ordering — this will not fit the standard non-S-Line A7
• Check your exhaust tip layout against the integrated outlets before ordering and again before adhesion — outlet spacing needs to match your car's tailpipe positioning
• Installation is reversible, but adhesive removal and re-prep may be required if pieces need repositioning
