2015-2021 Subaru WRX / STI VA - Rear Diffuser 1pc

Product Description

Transform the rear aesthetic of your VA Subaru WRX or STI with the NexaNovo 1-Piece Rear Bumper Diffuser. Specifically engineered for the 2015–2021 chassis, this sleek, unified aero component replaces the understated factory trim with an aggressive, multi-finned profile that perfectly captures the "street-spec" performance look.

Key Features

• Unified 1-Piece Design: Unlike multi-piece shark fin kits, this diffuser features a single-piece construction that spans the center section of your rear bumper. This provides a cleaner, more integrated "OEM+" look with perfectly symmetrical vertical strakes.

• Aggressive Aero Styling: Featuring four pronounced vertical fins, this diffuser visually lowers the rear of the vehicle and creates a wider, more authoritative stance. It frames the quad exhaust outlets for a more finished, high-performance appearance.

• Premium Gloss Black Finish: Manufactured from high-grade, impact-resistant ABS plastic with a deep gloss black finish. The surface is treated with a UV-resistant clear coat to protect against fading and "chalking" caused by road debris and exhaust heat.

• Signature VA Series Fitment: Precision-molded to match the factory bumper lines of:

  • Subaru WRX (Base, Premium, Limited)

  • Subaru WRX STI (Base, Limited, Series.White, Series.Gray)

  • Years: 2015, 2016, 2017, 2018, 2019, 2020, 2021.

• Durable & Heat Resistant: Engineered to withstand the high temperatures generated by your exhaust system. The ABS material is rigid enough to maintain its shape at high speeds while being flexible enough to resist minor road impacts.

• Secure Installation: This diffuser is designed for a secure, flush fit. While high-strength adhesive tape helps with positioning, drilling and mechanical hardware (included) are required to ensure the unit remains secure under high-speed wind pressure.

Product Specifications

FAQ:

Will this fit with my oversized aftermarket exhaust tips?

Yes! The 1-piece center diffuser is designed to sit between the exhaust cutouts, providing plenty of clearance for popular 4" and even 4.5" exhaust tips from brands like Invidia, Remark, or AWE.

How is this different from the "Shark Fin" kits?

This is a single solid unit that covers the flat area between the exhausts, providing a more cohesive and structural appearance compared to individual fins that are taped on.

Does it require removing the rear bumper?

No, you can install this with the bumper on the car. We recommend using a jack or ramps to provide enough clearance for the drill to secure the mounting screws into the bottom of the plastic bumper cladding.

Is it compatible with a rear tow hook?

Depending on the brand of your tow hook, minor trimming of the diffuser may be required if the hook passes through the center section of the bumper.
