Dinan sport mufflers are designed to compliment the F3x and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. Simple bolt in installation frees up 4HP and 3 lb/ft of TQ.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere.

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. Features: More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM Helmholtz chamber to reduce drone Enjoyably louder, sportier sound Twin 89mm (3.5") laser engraved, polished or ceramic black exhaust tips 100% 304 stainless steel construction Uses the factory brackets and hangers for a factory-like fitment
