Granatelli 4.0in Aluminum Mating Male to Female Flanges w/V-Band Clamp/O-Ring Seal

When you're fabricating a custom exhaust system, especially one that needs to be easily removable or sealed tight, a V-band flange setup is a solid choice. This kit from Granatelli Motor Sports gives you a 4-inch diameter mating male-to-female flange set made from aluminum, designed to create a strong, leak-free connection.

The interlocking male and female halves help ensure proper alignment when you're putting the system together, and the included O-ring seal is key to preventing exhaust leaks. This setup uses a V-band clamp to secure the two halves together, making it a popular choice for turbo downpipes, exhaust sections that need to be removed for maintenance, or anywhere a robust, sealed joint is required. The aluminum construction keeps the weight down, which can be a consideration in custom builds.

This kit comes complete with the flanges, the O-ring seal, and the V-band clamp needed to make the connection. It's a well-built component for custom exhaust work.
