Description
Overview
The Flowmaster Header Collector Ball Flange Kit is a high-performance connection solution engineered to replace typical three-bolt flange-style header connections. Instead of relying on gaskets that can burn out, crack, or blow through over time, this ball flange design creates a leak-free, gasket-free seal that holds up to the demands of a serious exhaust system. Sold in pairs, this kit gives you a matched set of ball-and-socket flanges to complete both sides of your header collector connection.
Each end of the kit features a 3.00-inch inside-diameter slip-fit connection, making installation straightforward for fabricators building or upgrading a custom exhaust. The spherical ball flange interface allows for slight angular adjustment during assembly, helping you dial in proper alignment between the header collector and the rest of the exhaust piping. Please note that welding is required to complete the installation.
Key Benefits
Constructed from durable 16-gauge aluminized material in a clean gray finish, this flange kit is built to resist the heat and corrosion that exhaust components face every day. The header flange thickness measures a substantial 3/8-inch, providing a rigid, warp-resistant mating surface that maintains a tight seal even under repeated heat cycling. The reversible design adds flexibility to your build, and the necessary bolts and studs are included so you have the hardware needed to bolt the connection together.
- Gasket-free, leak-free ball flange connection replaces standard three-bolt flange setups
- 3.00-inch inlet and outlet inside-diameter slip-fit connections for straight-pipe fitment
- Aluminized 16-gauge construction in a gray finish for heat and corrosion resistance
- Heavy 3/8-inch header flange thickness for a rigid, warp-resistant seal
- Reversible design with bolts and studs included
- Sold in pairs to complete both sides of the collector connection
Options & Configuration
This ball flange kit is offered in various sizes to suit different exhaust builds, with the 3.00-inch inlet and outlet configuration providing a matched straight-pipe connection on both ends. Choose the size that fits your header collector and exhaust piping to ensure a clean, precise slip-fit assembly. Both the inlet and outlet use a straight-pipe connection type, keeping the interface simple for custom fabrication.
Fitment & Installation
Designed for high-performance exhaust applications, this Flowmaster kit is classified as a High Performance grade component within the Brackets, Flanges and Hangers category. The 3.00-inch height, flanged attachment method, and included hardware make it a purpose-built piece for anyone upgrading from a leak-prone gasketed connection. Because welding is required to secure the slip-fit ends to your piping, this kit is best suited for installers and fabricators comfortable with exhaust welding. The result is a robust, sealed connection engineered to keep your exhaust flowing cleanly and quietly at the collector.
