    Description

    Race Inspired Styling. Add an aggressive race car inspired appearance to your 2015-2017 Premium Package Mustang by installing a MP Concepts Quad Exhaust Rear Diffuser. Designed for use with aftermarket quad exhaust systems, this Diffuser nicely compliments the lines of your Premium Package equipped Mustangs rear bumper cover.

    Quality Construction. MP Concepts manufactures their Quad Exhaust Rear Diffuser from injection molded acrylonitrile butadiene styrene (ABS) plastic using the original OEM CAD data from Ford to ensure a perfect fit. ABS is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driven vehicles. This Rear Diffuser is completed in a fine grained stippled texture for a factory look that helps to hide the appearance of rock and stone impacts.

    Straight Forward Installation. Installation of the MP Concepts Rear Diffuser is simple and straight forward. However, it will require permanent modification to the stock rear bumper cover to remove a section of the factory diffuser. Installation can be completed in about two hours. Reuses factory reflectors.

    Backup Sensor Compatible. This MP Concepts Rear Diffuser can be installed on Mustangs equipped with or without factory installed back-up sensors and will not affect sensor operation.

    Application. This MP Concepts Quad Exhaust Rear Diffuser is specifically designed to fit 2015-2017 GT and EcoBoost Mustangs equipped with the factory Premium Chassis Packages only (Trim Levels: 200A/201A/400A/401A). Intended for use with aftermarket quad exhaust systems.
