Hedman 2.5" Exhaust Collector Reducer Pair — 2.5" Inlet to 2.5" Outlet, 3-Bolt Ball-and-Socket Flanges, Steel

Hedman Hedder Collector Reducer is a pair of steel exhaust connectors that transition 2.5" inlet to 2.5" outlet with 3-bolt ball-and-socket flanges and included hardware for an airtight, bolt-on fit.

This Hedman Hedder Collector Reducer is designed for precise exhaust routing where a compact, durable transition is needed. Manufactured from mild steel and supplied as a pair, the reducers include the flanges, gaskets and bolts required to join a 2.5-inch collector to a 2.5-inch tail section or mid-pipe. The ball-and-socket 3-bolt flange allows for minor alignment adjustments during installation while the steel construction provides strength for under-car use; the parts arrive in natural finish ready for welding or clamp-on installation depending on your exhaust layout.

How does the 3-bolt ball-and-socket flange improve fitment?

The ball-and-socket flange gives a small amount of articulation so misaligned pipes still seal when bolted together. That design helps prevent leaks at the connection point without forcing over-flexing of the tubing or gaskets.

• 3-bolt pattern for even clamping pressure
• Ball-and-socket geometry accommodates slight angular mismatch
• Includes gaskets to ensure a reliable seal
• Hardware provided for a complete bolt-on joint

Will these reducers work with my 2.5" exhaust components?

Yes — the part size is a direct 2.5" inlet to 2.5" outlet transition, intended to mate with other 2.5" tubing or collectors. They're sold as a pair so you can repair or extend both sides of a dual-outlet system or replace two worn connectors at once.

• True 2.5" internal diameters on both inlet and outlet
• Compatible with standard 2.5" exhaust tubing and collectors
• Supplied in pairs for dual applications or spares
• Mating flanges and gaskets included for straightforward assembly

What materials and hardware are included, and how durable are they?

The reducers are constructed from mild steel with a natural finish and come complete with all necessary flanges, gaskets, and mounting hardware. Mild steel provides solid strength and can be welded, though you may choose to coat or paint the parts to resist corrosion over time.

• Mild steel construction for strength and ease of welding
• Natural finish ready for protective coating or painting
• Complete hardware kit: bolts, nuts and gaskets included
• Designed for under-vehicle exhaust conditions and clamp or weld installation

How simple is the installation process for a home mechanic?

Installation is straightforward for most DIYers: position the reducer, align the ball-and-socket flange, insert the gasket, and tighten the bolts. Because the kit includes all necessary hardware, you won’t need to source extra parts to complete the joint.

• Bolt-on assembly with included 3-bolt hardware
• Ball-and-socket flange reduces need for precision alignment
• Can be welded in place for permanent installations
• Clearances and orientation adjustable during fitment

Who is this for? The Hedman Hedder 2.5" Collector Reducer pair is ideal for enthusiasts, professional shops, and DIY mechanics who need a reliable 2.5" to 2.5" transition with a forgiving 3-bolt ball-and-socket flange. Choose this set when replacing worn connectors, re-routing an exhaust, or building a custom system where ease of alignment and included hardware help speed up installation. Note: these are mild steel, natural finish parts; if long-term corrosion resistance is required, plan to coat, paint, or use stainless alternatives.
