Header Collectors 2.5" 3 Bolt Flange Inlet 2.5" Outlet Pair

Complete your custom exhaust system with these stainless steel 2.5-inch exhaust header collectors featuring integrated oxygen sensor bungs. Designed for headers equipped with standard 2.5-inch 3-bolt collector flanges, these collectors provide a durable connection point between your headers and exhaust system while allowing convenient installation of oxygen sensors for EFI and tuning applications. Each collector features a full 2.5-inch inlet and 2.5-inch outlet, helping maintain exhaust flow without reducing collector diameter. The welded oxygen sensor bung includes a threaded plug and is ready for narrowband or wideband oxygen sensor installation. A unique advantage of this design is the fixed welded flange. Because the collector can be bolted to the header in multiple orientations, installers can select from three different clocking positions to better position the O2 sensor and improve clearance around chassis, steering, transmission, and exhaust components. These collectors are commonly used on LS swap shorty headers, custom street rod builds, muscle cars, hot rods, race cars, engine swaps, and fabricated exhaust systems utilizing a standard 2.5-inch three-bolt collector flange. Constructed from corrosion-resistant stainless steel for long service life and durability. Package Includes: 2 Stainless Steel Header Collectors 2 Copper Collector Gaskets 6 Collector Bolts 6 Locking Flange Nuts 2 O2 Bung Plugs Installed

• DESIGNED FOR 2.5" HEADER COLLECTORS: Fits exhaust headers equipped with standard 2.5-inch 3-bolt collector flanges. Features a full 2.5-inch inlet and 2.5-inch outlet to maintain exhaust flow while providing a convenient connection point for custom exhaust systems
• INTEGRATED OXYGEN SENSOR BUNG: Each collector includes a welded O2 sensor bung with threaded plug installed. Suitable for LS swaps, EFI conversions, wideband tuning, aftermarket engine management systems, and custom exhaust fabrication projects
• MULTIPLE CLOCKING POSITIONS: The welded flange design allows the collector to be rotated into three different bolt positions during installation. This helps position the oxygen sensor for improved clearance from floor pans, frame rails, steering components, transmission crossmembers, and other obstacles commonly encountered during engine swap projects
• COMPLETE PAIR WITH HARDWARE: Includes (2) Stainless steel header collectors, (2) 2.5-inch collector gaskets, (6) Collector bolts, and (6) Flange nuts. Everything required to install both collectors onto compatible 3-bolt exhaust headers
• COMPATIBLE WITH LS SWAP SHORTY HEADERS: Commonly used with LS swap shorty headers, street rod headers, hot rod exhaust systems, muscle car projects, custom fabricated exhaust systems, and other applications utilizing a standard 2.5-inch 3-bolt collector flange
