Rather than replace the full diffuser and have potential fitment challenges with various exhaust options Dinan has opted to retain the factory gloss black lower portion of the diffuser and only replace the upper diffuser surround with a carbon fiber accent piece. This solution not only guarantees the carbon cosmetics will always play well with any personalization of the exhaust that is adopted but also offers an economical option compared to much pricier alternatives. Together with the Dinan Rear Side Splitters, the combination creates a "full" rear diffuser that is restrained but elevated and creates a nuanced OEM+ option for the marketplace.
Features:
- 2x2 gloss twill dry carbon fiber (pre-preg) manufactured to be impact resistant, durable and strong
- Clear coated for maximum UV protection and fade resistance
- Utilizes factory mounting tabs for an easy installation with a clean fit and finish
- Pair together with the Dinan Rear Side Splitters to complete the full rear look

Nice vest at a good value
Color: Black, Size: Large
Nice vest out of the bag. Fit is good. I’m 5’10” 200lbs with a bit of a beer belly. I’m not muscular at all. Use that description as a comparison to your own body. I can’t speak to the overall quality and how long it will last but for my use going to a black tie gala this is a really nice vest. Happy with my purchase.

Mixed Review. Let me explain.
Color: Black, Size: Large
I ordered both the light gray and black vests in Large. Each one was delivered separately, not sure why, but a day or to late on one was no big deal. I got the gray vest on time. Label reads "COOFANDY." Fits perfectly. The black vest arrived late. Label reads "PAUL JONES Since 1958." Vest was too small. A different material was used on the back section of the vest, which is common, but not what I wanted. The gray vest was constructed of the same material used on the front. I'm not sure if this was a packing error or what, but I returned the black vest for a refund. The verdict: Great, well-constructed, true fit vest with the COOFANDY label. Not so well-constructed (a couple of the button holes had loose threads), small fit vest with the PAUL JONES label. Be sure to check that label. Five stars for the COOFANDY minus two stars for the goofed-up quality control of the seller.
