Dinan"s Free Flow Stainless Exhaust for the BMW F30 340i

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.

Dinan Spring Set and Handling Kit for the BMW F30 340i (RWD)

Suspension systems should not only transform the stance of a vehicle, but also maintain ride quality and improve upon handling. That is exactly what Dinan suspension systems are well known for. This goal is accomplished by pairing springs sets with bump stops and/or spring perches to maintain suspension travel, resulting in a smooth ride while also improving mechanical grip and handling.

Dinan Performance Spring set for BMW F30 340i (RWD)

Dinan’s Performance Spring set for the F30 340i (non xDrive) provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the 340i by a full 1″ in front and 1″ in the rear for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot peened for stress relief to last the life of the car. The 25% increase in stiffness in front and 34% increase in the rear will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip, for high speed driving situations that will inspire confidence in your car’s capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at speeds as low as 20 mph, up to the top speed of the vehicle.

Benefits of the Dinan Performance Spring Set for the F30 340i (non xDrive):

•  25% increase in spring stiffness in front, 34% increase in the rear.


• Lowers the vehicle 1″ in front and 1″ in the rear


• Preset to prevent spring sag


• Compatible with both conventional and factory electronic shocks

Dinan Supplemental Ride Quality & Handling Kit for BMW F30 340i (RWD)

This additional kit includes tuned, progressive rate bump stops that maximize suspension travel on the lowered car for improved handling capabilities and ride quality when compared to just a spring set. By allowing for full compression travel within the spring the possibility of a sudden “bottoming out” is negated, a common unwanted side effect when lowering a vehicle.  Bump stops also have the added benefit of optimizing the spring rate rewarding those that use them with added mechanical grip and cornering power. Simply put, the Dinan supplemental ride quality and handling kits amplify performance and comfort when paired with performance spring sets.
