Description
Dinan engineers designed the BMW F33/F36 440i exhaust to improve 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. The enhanced tone, along with the additional burbles and pops, is simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or "drone" at low RPM.
Built to exacting specifications to ensure a perfect fit using the factory hangers, this system is made from 100% 16 gauge 304 stainless steel to resist corrosion for years to come. The exhaust features twin 89mm (3.5") polished or ceramic black laser engraved exhaust tips, offering a tasteful high-performance look.
