System Details

  • Typical fitting time: Varies by configuration
  • ECE approval: Not specified on supplied price list
  • Variant pricing and manufacturer part number change with the selected configuration.

Built to order: Select the system configuration and tip finish carefully. The exact Milltek part number is shown as the variant SKU.

Bill's Take
The Defender is a great truck, but the factory setup leaves a lot of personality on the table. Milltek is one of my preferred exhaust choices because the systems fit properly, the finish looks OEM+, and you can usually pick the sound level and tip style instead of being stuck with one setup.
