To ensure compatibility with various exhaust setups, Dinan chooses a unique approach. We replace only the upper diffuser surround with a carbon fiber accent piece, leaving the factory gloss black lower portion intact. This not only guarantees seamless integration with personalized exhaust choices but also presents an affordable alternative compared to costlier options. When combined with our Dinan Rear Side Splitters, it forms a complete rear diffuser, offering a refined OEM+ solution for the market.
