Dinan’s free flow exhaust for the 340i and xDrive sedan improves exhaust flow by reducing back pressure. It also accentuates an exhaust note with a more purposeful tone complete with intoxicating burbles. The exhaust system is available with either polished tips or black tips, depending on your preference.
Dinan engineers designed the F30 BMW 340i exhaust to reduce back pressure, resulting in increased power output and a great sporty sound. The sound emitted can be civilized when you want it to be, and pleasantly aggressive under harder acceleration. Not only is the tone improved, but the additional pops and burbles that come with it are quite thrilling. Dinan also incorporates a Helmholtz chamber design that reduces resonance or “drone” at low RPMs.
The system is built to exacting specifications to ensure a 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″) polished or ceramic black exhaust tips for a tasteful, high-performance look.
