Dinan Free Flow Axle-Back Exhaust - 2016-2020 BMW 340i/440i

$1,299.95 $1,445.00

Dinan engineers designed the F30 340i and F32 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. 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") polished or ceramic black exhaust tips for a tasteful high-performance look. The factory computer-controlled exhaust valve is eliminated.

Good, confused a little as to why the 10% off code would not work for this item when I thought I read that it was off everything.
