Dinan Free Flow Stainless Steel Exhaust w/ Black Tips -BMW 340i 2016 340i xDrive 2016

Stainless Steel - Polished Tips - F30/F32; Dinan engineers designed this 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. Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or drone at low RPM. The system is built to exacting specifications to ensure the perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm (3.5 in.) polished or cermic black exhaust tips for a tasteful high-performance look. The factory computer-controlled exhaust valve is eliminated.;
