Kooks 2.5-Inch Stainless Steel Female Socket Flange for Ball & Socket Exhaust Systems
The Kooks 7105-AS-FEMALE 2.5-inch female socket flange is the factory-spec replacement or custom fabrication component for all Kooks 2.5-inch ball-and-socket exhaust connections, precision CNC-machined from T304 stainless steel with a smooth radius socket that mates perfectly with the Kooks 7105-AS-MALE ball (sold separately) for 15° of articulation in any direction while maintaining a leak-free seal under extreme heat and vibration.
Designed for mid-pipe or cat-back connections, this female socket flange welds directly to 2.5-inch OD tubing and accepts the high-temperature graphite gasket and heavy-duty Torca band clamp from the full 7105-AS kit. The 3/8-inch thick flange face with 3-bolt pattern ensures maximum strength and perfect alignment for 800+ HP applications.
