Dinan Free Flow Stainless Steel Exhaust w/ Black Tips – BMW 135i 2008-2013
Dinan’s free flow exhaust for the 135 improves exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be and pleasantly aggressive under harder acceleration. 100% stainless steel construction and exacting specifications ensure that the system fits correctly using the factory hangers and will resist corrosion for years to come. The design reduces overall weight as well and features two 3.5” black tips for a more high performance look.
