The F90 M5 has impressed users and critics alike with its awe-inspiring power, effortless delivery, and general embodiment of what BMW has always been about - refined performance. Form and function reign supreme from the factory in true German form. On the other hand, other aspects may not be as carefully cultivated. The stock exhaust note on the F90 M5 as an example, while no slouch, is probably best described as having a subdued aggressive note. Dinan believes for such a powerful and impressive car however that the vehicle deserves to be able to bellow a bit louder and more aggressively. The F90 M5 is the alpha on the public roads after all.
In order to achieve desired sound volume and tone, Dinan felt becoming of the F90 M5 the tubing was enlarged to 83mm (vs 80mm stock) to allow freer flow throughout the entirety of the system. The larger tubing is fed into a muffler that is typical of all Dinan exhaust design and utilizes absorption and reactive technologies designed to improve exhaust flow and reduce backpressure. The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration.

Shipping Coverage
EuroSpeed ships to customers across the United States and internationally. Shipping is included in the price of eligible products for your convenience and covers the initial cost of delivery to your destination.
Import duties, taxes, clearance fees, or customs charges required by your destination country are not included and remain the recipient’s responsibility.
Order Processing & Fulfillment
Every order is reviewed, processed, and prepared before shipment. Most in-stock products are processed within 1–3 business days, though some orders may take up to 5 business days depending on fulfillment location, product type, order volume, or courier pickup timing.
EuroSpeed stocks select high-demand products at our U.S. facility and international fulfillment centers. Because our catalog includes many vehicle-specific and specialty parts, not every product is held in-house at all times.
Some orders may ship through our trusted fulfillment network, which may include verified manufacturing partners, authorized distributors, regional warehouses, and international fulfillment centers.
- Orders may ship from a U.S. warehouse, international warehouse, manufacturer, or authorized fulfillment partner.
- Some products may require additional handling, processing, production, or quality-check time before shipment.
- Orders enter fulfillment shortly after being placed and may no longer be eligible for cancellation once processing, production, or shipment preparation begins.
Custom, Made-To-Order & Oversized Items
Custom, made-to-order, and oversized product categories may include carbon fiber steering wheels, hoods, trunk lids, fenders, front lips, splitters, side skirts, diffusers, bumpers, body kits, widebody components, select spoilers, rear wings, and other large carbon fiber components.
Many carbon fiber items are made to order. Some products may already be stocked and ready to dispatch when available, but if inventory is unavailable, your purchase reserves the next available production slot instead of waiting for a separate restock listing.
Production time: Production can take 1–4 weeks depending on product type, selected options, finish, current queue, and quality-control timing.
Shipping time: Shipping can take 2–10 weeks depending on item size, freight method, destination, customs processing, carrier delays, warehouse transfers, and final delivery location. Carbon fiber steering wheels typically ship faster, with shipping usually taking 3–7 business days after dispatch.
By purchasing custom, made-to-order, or oversized items, you acknowledge and accept the extended production, fulfillment, and shipping timelines associated with these products.
Tracking Updates & Delays
All orders receive a tracking number once generated by the courier. Tracking may take 2–3 business days after dispatch to show movement in the courier’s system.
Certain international, oversized, or freight shipments may show limited updates during transfer between fulfillment locations, warehouses, customs, or final-mile carriers. In some cases, tracking is provided or begins updating once the item reaches a regional warehouse, local carrier, or final delivery network.
Shipping timelines are estimates and are not guaranteed. Delays caused by high order volume, weather conditions, customs inspections, carrier disruptions, production queues, warehouse transfers, holidays, or other external factors may occur and are outside of EuroSpeed’s direct control. These delays do not qualify for cancellations or refunds unless the carrier officially marks the package as lost.
Delivery Responsibility
Upon delivery, carefully inspect the item for visible defects or damage before signing for it. If the item is damaged or not as expected, do not accept the package. Once a damaged or defective product is accepted, EuroSpeed cannot cover return shipping costs.

EuroSpeed is not responsible for failed deliveries, additional shipping costs, lost packages, or refunds caused by incorrect shipping information, failure to accept delivery, or failure to collect a package from the post office or carrier pickup location within the required time frame.
Customs, Duties & Import Fees
EuroSpeed’s free shipping policy does not include import fees, taxes, duties, clearance charges, or other fees required by your destination country. These charges are the responsibility of the recipient, and EuroSpeed is not responsible for any duties or taxes requested by local customs.
Most shipments clear customs automatically through the shipping provider. However, if additional information is needed to complete the process, our team will assist where possible to help ensure a smooth resolution.
If customs clearance fails and the item is returned or destroyed:
- EuroSpeed reserves the right to deny refund claims.
- Returned items may incur return shipping fees, which will be deducted from any eligible refund.
