Description

The Dinan D660-0091 Free Flow Valved Axle-Back Exhaust system for BMW enhances exhaust note and performance with a valved design, allowing for an aggressive sound under acceleration and a quieter tone at cruise. It features either polished or ceramic black tips and is constructed from T304 stainless steel with a brushed finish. This system is engineered to reduce back pressure and improve exhaust flow, contributing to modest horsepower and torque gains. It is a direct bolt-on installation using factory hangers, requiring no cutting or welding.
