This rear carbon fiber diffuser will add to the style of your M vehicle, giving it a much sportier and aggressive appearance from the rear. The M3/M4 are great looking vehicles, nearly flawless, but there is always room for improvement! Made from high quality carbon fiber and built for a tight, stock-like fitment, this diffuser is the way to go when you want to add it by itself or when upgrading your exhaust system. This can help performance exhaust tips stand out even greater compared to the stock diffuser. Finish comes in either: High Gloss Matte
