Description
The Dinan axle-back exhaust changes the sound and rear appearance of 2014-2016 BMW 435i. This version supplies black-finished exhaust tips.
A tuned Helmholtz chamber addresses resonance in the lower engine-speed range while the freer-flowing muffler arrangement gives the exhaust a stronger voice. Sound remains dependent on load, transmission behavior and the other exhaust sections.
