S Style Rear Apron Diffuser with Quad Tips for S-Line Fastbacks
Transform your rear profile with the s style rear apron diffuser quad tips set from Kubay Design. We engineered this custom lower rear valance specifically for late facelift executive fastback platforms produced between 2016 and 2018 equipped with factory S-line exterior trim. As a result, this complete rear apron diffuser package upgrades standard sport rear styling into a refined performance stance featuring subtle central diffuser fins and quad exhaust tailpipe finishers.
Our manufacturing specialists injection-mold every rear diffuser section using high-impact, flexible ABS plastic accompanied by stainless steel quad tailpipe assemblies. Therefore, this lower rear valance withstands high-speed road debris, exhaust heat, and extreme winter road salt exposure without cracking, melting, or warping over time. In addition, OEM mounting clip locations ensure a precise fitment against factory S-line mounting tabs. You can explore complete exterior styling accessories in our Shop or inspect custom conversions on Our Projects.
Engineered Valance Architecture and Quad Exhaust Finishers
We precision-craft every Kubay Design rear apron diffuser unit to deliver authentic sport executive presence across luxury fastback vehicles. Because of this targeted component molding, swapping out your original lower valance remains completely intuitive.
The complete conversion unit includes one black rear apron diffuser panel, matching lower mesh inserts, quad exhaust tip finishers, tailpipe adapters, and inner mounting brackets. Furthermore, deep black surface finishing guarantees complete visual harmony with surrounding lower aprons and tail lamps.
Vehicle Compatibility and Custom Installation Notes
This S-style rear valance package offers direct OEM-style replacement fitment across 2016–2018 facelift executive fastback platforms equipped exclusively with S-line rear aprons. Please note that this unit does not fit standard non-S-line rear covers.
Because rear parking distance sensor brackets and hands-free tailgate release sensors vary across regional specification packages, we strongly recommend submitting your Vehicle Identification Number (VIN) and current rear photos for fitment confirmation. Therefore, these custom interior packages for W447 vans and executive fastbacks deliver complete visual coordination inside and out.

Worldwide Freight and Multi-Layer Packaging
We pack every rear apron diffuser securely inside protective cushioned boxes and reinforced cardboard shipping containers with foam surrounds to safeguard the diffuser fins, exhaust tips, and mounting tabs during international transport. In addition, we arrange global express air delivery via UPS or DHL with full tracking provided after dispatch.
