Collector 3in To 2.5in 3 Bolt

The Hedman Collector 3in to 2.5in 3-Bolt exhaust collector reducer is a precision-engineered component designed for custom exhaust system fabrication and modification. This dual-piece collector set performs a critical function in exhaust manifold design: transitioning flow from a 3-inch inlet diameter down to a 2.5-inch outlet while maintaining structural integrity and minimizing turbulence at the junction. The three-bolt flange configuration provides a secure, repeatable connection point for manifold-to-downpipe integration, essential for builders requiring precise fitment tolerances.

Built from durable steel with a natural finish, each unit weighs 2.64 lbs and arrives with gasket seals included—eliminating the need for separate gasket sourcing during installation. The 3-bolt flange design is standard across most high-performance exhaust applications, ensuring compatibility with both OEM and aftermarket manifold designs. Proper gasket engagement at the reducer junction is critical for preventing exhaust leaks; the included gaskets are sized to accommodate the dimensional transition and standard bolt-hole spacing. Steel construction provides the thermal stability necessary for continuous high-temperature service, while the natural finish allows for custom coating if integration with a specific exhaust system aesthetic is required.

This collector reducer serves fabricators, restoration specialists, and performance exhaust builders who need dependable transition components. Whether you're custom-fitting a downsized exhaust system, adapting manifold outlet diameter to match downstream piping, or rebuilding a multi-piece collector assembly, the 3in to 2.5in reducer is a foundational part that demands reliable construction and correct geometry. The pair configuration allows flexibility in dual-system builds or provides a spare for ongoing projects. Sourcing quality reducer components with verified gasket compatibility eliminates guesswork during assembly and reduces the risk of post-installation exhaust leaks that compromise both performance and durability.
