While sound is of the utmost importance for any exhaust system the fit and finish are nearly equally as vital. The system is built to exacting specifications to ensure perfect fit using the factory hangers and is made from 100% 16 gauge 304 stainless steel that will resist corrosion for years to come. What is most different about the 540i system however is a completely new tip design from anything Dinan has done prior. The use of twin, massive quadrilateral, black ceramic coated and engraved angled tips are hard not to to take notice of. With over 8" of width and 4" of height per tip, the rear of the 540i assumes a more aggressive demeanor with the Dinan exhaust system. A high-performance look that marries well with the tonal makeover.
