Show original supplier description
The collector on this flange set measures 3 inches in diameter and reduces to 2-1/2 inches in tubing diameter, facilitating a secure transition within your exhaust setup. The slip-fit connections on both ends simplify assembly, making installation more straightforward. Constructed from durable 16-gauge aluminized steel, these flanges are built to withstand the rigors of exhaust system operation, offering excellent resistance to corrosion and wear for long-lasting performance. Installation of the Flowmaster Header Collector Ball Flange requires welding to ensure a permanent and robust connection. The set comes complete with all necessary hardware, ready for integration into your existing or custom exhaust system.
