2002-07 | Full Rear Diffuser (Carbon Fiber)

Vehicle Fitment: GD | Sedan Only | 2002-2007 Impreza WRX / STI

On the carbon fiber version, the diffuser is made with BlackTop Aero’s unique “SEMI Dry Carbon Process”. They have developed a new way of making carbon fiber products to be lighter and stronger; by applying the carbon fiber while the products are still inside the mold. This process will allow them to produce thinner and lighter products and able to place the carbon weaves in a better alignment. This is needed for the HKS diffuser due to the curves that need to be perfect in order to be fit flush on the bumper.

Other CF products, including BlackTop Aero lips and SEIBON hoods are wet carbon process where the shape of the product is built with fiberglass then taken off of the mold and wrapped in carbon fiber.

The carbon fiber diffuser is produced uncut, like the fiberglass version. An angled exhaust bracket can be supplied to those who need one.

All Hardware Included:
Each diffuser comes with a bracket for installation. A custom bracket will be provided for customers with angled exhaust exit. Please specify when ordering if you have an angled exhaust.

Note:
- Stock bumper requires trimming. Diffuser will be sent uncut.
- Will only fit on Sedan. Will not fit on Wagon rear bumpers.
- Fits most exhausts. See above if your Subaru has an aftermarket angled exhaust.

* Also available in Fiberglass.
