Manufactured in the United States from raw steel and supplied with matching gaskets, the pair simplifies installation where a smaller downstream diameter is required. The natural finish preserves the bare-steel appearance, ready for custom coating or wrapping if desired.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this reducer fit into an exhaust setup?\u003c\/h3\u003e\n\u003cp\u003eThe Hedman collector reducer bolts directly to a 3-bolt header flange and steps the outlet down to a 2.5-inch outer diameter, providing a reliable mechanical and flow transition. It’s intended for applications where the header collector and the downstream pipe use different diameters or when mating to aftermarket mufflers or adapters.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch inlet matches common header collector sizes.\u003c\/li\u003e\n  \u003cli\u003e2.5-inch OD outlet fits standard 2.5\" exhaust tubing or slip-fit adapters.\u003c\/li\u003e\n  \u003cli\u003e3-bolt flange ensures a tight, repeatable connection to headers.\u003c\/li\u003e\n  \u003cli\u003eIncludes gaskets to reduce leaks at flange joints.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the construction and compatibility details?\u003c\/h3\u003e\n\u003cp\u003eBuilt from stamped or formed steel in a natural finish, each reducer is supplied as part of a matched pair and intended for vehicle-specific applications—check fitment before ordering.

No exotic tools are required, though a torque wrench and anti-seize on fasteners will help ensure a long-lasting connection.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eComes with flange gaskets to prevent exhaust leaks at the joint.\u003c\/li\u003e\n  \u003cli\u003e3-bolt flange pattern matches standard header collector mounting points.\u003c\/li\u003e\n  \u003cli\u003eCan be welded or clamped to the downstream 2.5\" pipe.\u003c\/li\u003e\n  \u003cli\u003ePair packaging supports dual-header installations without additional purchases.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? This Hedman Hedders collector reducer pair is for DIY mechanics, custom exhaust builders, and performance hobbyists who need a reliable, ready-to-install transition from a 3\" header collector to 2.5\" outlet piping. It suits vehicle-specific header retrofits, replacement of damaged collectors, or custom exhaust projects where a stepped-down outlet is required, and where a durable steel component made in the USA is preferred.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this reducer include gaskets and hardware?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the pair ships with matching 3-bolt flange gaskets; bolts are not typically included, check fitment requirements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I weld or clamp the 2.5\" outlet?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the 2.5\" OD outlet can be welded, clamped, or slip-fitted to standard 2.5\" exhaust tubing.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Hedman","offers":[{"title":"Default Title","offer_id":67586539225273,"sku":"B000COD2BI","price":116.68,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/hedman-collector-reducer-front-flange.jpg?v=1790486367","url":"https:\/\/redleafauto.ca\/products\/hedman-hedders-collector-reducer-3-inlet-to-2-5-od-outlet-3-bolt-flange-steel-pair-with-gaskets","provider":"Redleaf Auto","version":"1.0","type":"link"}
