Finishes
Black - This black finish is sleek and stealthy. You can also use this variant to have a local painter paint match the diffuser or paint it a custom color.
Silver - The original STI OEM diffuser is painted silver from the factory. This one is similar straight out of the box.
Carbon Fiber - A layer of carbon fiber surrounds this model and really makes it stand out.

Just like OEM but...
By Patrik November 19, 2022Fitment was very good, the finish was just the OEM piece. Although there where some mysterious holes in the spoiler that i had to JB weld shut to prevent water from entering inside. Overall, it looks great! And i highly recommend deep 14mm (9/16) sockets and a breaker bar for the crash beam bolts!

By KennyJ540 June 8, 2019Fitment was spot on, and really easy to install. Just make sure you have a breaker bar or impact gun to break the crash beam bolts loose. Only complaint with this product is the mounting hardware rusts almost instantly and the diffuser itself fills with water somehow????

Great rear visual
By Edgar March 16, 2017It took a while to install due to some tools I didn't have but overall is not complicated to mount this diffuser. IT gives a different view to the rear end. Now saving up to put a Lip to my baby =)
