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.

        Can I install it on my 2016 non premium mustang ecoboost?

        • The TruFiber Carbon Fiber Trim piece is designed to be a direct replacement of the plastic rear valance panel featured on the GT and EcoBoost Mustangs with the Premium Package Bumper. Unfortunately this trim piece will not fit on Non-Premium Bumpers

            Fits like a glove

            the whole bumper needs to be removed, a little tricky, but after that, the diffuser fits in the right places and looks awesome, thanks American Muscle.

            I have purchased several CF pieces for my Mustang and the finish is always the same, smooth and glossy and looking great. However, this item shipped direct from manufacture and the finish on the piece is rough and has appearance like a sticker placed on original trim. Called AM but they could not help. I sent message to TruFiber on their website, since they have no phone number, and have been waiting a week for any kind of response. Probably the last TruFiber purchase for me.

            CF Diffuser

            Both the rear trim piece and diffuser in carbon fiber are quite simply a perfect fit and offer a stunning appearance to my 2016 GT. Thanks AM.

            Terrific Quality Carbon Fiber Rear Diffuser. Looks great on my car. Took my vehicle to a few car meets and every Mustang owner there wanted to know where I bought my diffuser.
