2014- 2018 BMW 328D N47 Exhaust Kit

Most NAT Performance exhaust systems are built to order. Standard orders typically ship within 10 business days. Rush orders are prioritized and typically ship the next business day. Once your order ships, you will automatically receive a tracking email.

There are two timelines involved.

Production time:

Most exhaust systems ship within 10 business days.

Transit time:

Once shipped, delivery typically takes:

• 3–5 business days within the United States (standard shipping)

• 1–2 business days with rush/express shipping depending on your location

Tracking information is emailed automatically once your order ships.

Most NAT Performance exhaust systems are built in production batches. Your order may still be in the current production queue and will ship within the standard 10 business day timeframe. Tracking will be emailed automatically once your order ships.

Most NAT Performance exhaust systems are built to order rather than stocked on shelves. This helps maintain consistent quality and ensures proper fitment. Standard orders typically ship within 10 business days, while rush options may ship sooner.

Tracking is automatically emailed when your shipping label is created. If you haven't received tracking yet, your order is likely still in the production queue.
