Description:
Dinan Free Flow Exhaust with Black Tips for the 540i sedan improves exhaust flow by reducing back pressure and accentuates an exhaust note with a more purposeful tone complete with intoxicating burbles. Utilizing the same muffler as its B58 siblings the G30 540i exhaust 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 hard acceleration. Not only is the tone improved but the additional burbles and pops that also accompany it are simply intoxicating. While on the exterior the sound may be viewed as aggressive the inside of the cabin is still civil courtesy of an incorporated Helmholtz chamber design that reduces resonance or drone at low RPM. While sound is of the utmost importance for any exhaust system the fit and finish are nearly equal
