Exhaust Hardware Refresh Kit
$9.66

Keep your classic or modern BMW track-ready and leak-free with this Genuine BMW Exhaust Flange Hardware Kit. Perfect for servicing factory setups or completing a performance exhaust install, this kit replaces tired hardware at a critical high-heat junction. Reusing old, heat-cycled exhaust springs and soft copper nuts can lead to loose connections and performance-robbing exhaust leaks. This factory refresh kit bundles an original M8 self-locking copper flange nut with a fresh exhaust compression spring, ensuring your exhaust downpipe or midsection stays securely sealed despite relentless track use and road vibration.

Key Features

  • Factory Fresh Integrity: Genuine OEM components ensure strict factory-level fitment and reliability.

  • Vibration Resistant: Elliptical flange nut locks securely onto the exhaust stud to resist backing off.

  • Advanced Thermal Tolerance: Copper construction prevents the nut from seizing or cracking under extreme operating temperatures.

  • Eliminates Extra Washers: Flanged nut design simplifies the installation process with built-in surface contact.

  • Consistent Clamping Action: Sturdy compression spring provides exact tension to prevent exhaust joint separation.
