    Get Noticed. With the over abundant use of black plastic trim on modern day vehicles, it leaves most car enthusiasts hoping there are aftermarket options to choose from. Leave it to Trufiber to bring you a show stopping carbon fiber upgrade for your Premium S550's Rear Diffuser. Designed as a direct replacement, you can change the rear of your 2015-2017 Mustang from drab to fab in no time. With the trim extending over the exhaust outlets and around the center diffuser, it will add a subtle yet killer appearance to really get you noticed. Combine this with Trufiber's CF Rear Diffuser (sold separately) for a complete overhaul and bring your upgrade full circle.

    Real Vacuum Infused Carbon Fiber. This one piece Trufiber Rear Diffuser Trim features an amazing 3K, 2x2 Twill Weave design that has been made out of real, vacuum infused carbon fiber. Finished off with a clear coat that incorporates UV protection for superior defense against Mother Nature, this trim will certainly improve the rear styling of your Mustang. This diffuser trim can also be painted at your local shop for a more personalized splash of color out back.

    Easy Installation. This high quality Carbon Fiber Rear Bumper Trim is crafted to be a direct fit replacement of your factory Premium Pack diffuser trim and will utilize the stock hardware. Adding some personalization to the rear of your S550 couldn't be any easier.
