Frequently Asked Questions
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
