Core offering

Hedman Hedders, the flagship brand of Hedman Performance Group, manufactures tubular exhaust headers for classic American cars and trucks since 1954, offered in mild steel or T304 stainless steel with proprietary HTC or BLACK-MAXX ceramic coating finishes. The group also manufactures complementary engine swap components, engine mounts, transmission mounts, oil pans, cooling system parts, and drivetrain components under the Trans-Dapt and Hamburger's brands, plus complete Engine Swap-In-A-Box kits that bundle headers, mounts, oil pans, and hardware as a single integrated system.

Product overview

Hedman Performance Group is a multi-brand automotive performance parts manufacturer comprising three sub-brands: Hedman Hedders (exhaust headers, flagship brand since 1954), Trans-Dapt Performance Products (engine swap mounts, transmission components, and Engine Swap-In-A-Box kits since 1959), and Hamburger's Performance Products (billet aluminum oiling system components and LS swap products since 1979). The company operates as a platform of complementary performance parts that work together in engine swap and performance upgrade applications. The core product line centers on Hedman Hedders exhaust headers (available in long tube, mid-length, shorty configurations in mild steel or T304 stainless steel with HTC or BLACK-MAXX ceramic coating options) supported by Trans-Dapt's engine swap motor mounts, transmission mounts, and complete swap kits, and Hamburger's oil pans, filter relocation kits, and PERFECTMATCH powder-coated accessories. Additional product categories span cooling systems, drivetrain components, fuel systems, ignition systems, gaskets, fasteners, and shop equipment. The LS Swap Central hub consolidates all LS-specific products across the three brands for swap applications into classic American cars and trucks.

Emerging players

• COMP Cams: Performance valve-train and engine components brand within the broader Horsepower Inc./Holley ecosystem — adjacent rather than header-direct, but serves the same engine-swap/performance builder customer and competes for engineering mind-share.

Direct peers

• Doug's Headers: Long-standing aftermarket exhaust header manufacturer focused on classic and muscle car applications, selling through a similar dealer and enthusiast channel; comparable in product breadth, customer base, and Made-in-USA positioning.
• Patriot Exhaust (Patriot Performance Products): Aftermarket header and exhaust manufacturer serving the same classic American car/truck and engine-swap builder market as Hedman, with overlapping SKUs for LS swaps, Chevy, Ford, and MOPAR platforms.
• Hooker Headers: Direct competitor in aftermarket exhaust headers for muscle car and LS-swap applications, operating as a brand within Holley Performance Brands; competes head-to-head with Hedman on Camaro, Mustang, MOPAR, and truck header fitments.
• Stainless Works: Manufacturer of stainless-steel aftermarket headers and exhaust systems for muscle cars, trucks, and LS-swap builds — directly comparable to Hedman's T304 stainless header offering in materials, fitments, and customer profile.
• Mr. Gasket Company: Long-established performance aftermarket brand across gaskets, fasteners, headers, cooling, and dress-up accessories — directly overlaps Hedman's product categories (fasteners, gaskets, cooling, headers) and competitor set in the enthusiast channel.
• BBK Performance: Aftermarket performance header and intake manufacturer targeting late-model Mustangs, Camaros, and trucks; overlaps with Hedman on Ford and GM performance applications and shares the same enthusiast/DIY buyer.

Broad incumbents

• Holley Performance Brands: Large diversified performance-auto aftermarket platform whose brands (Hooker, Flowmaster, MSD, Earl's, etc.) span exhaust, EFI, ignition, and fuel systems — competes with Hedman as a broader portfolio but with vastly greater scale, capital, and distribution.
• Edelbrock Group: Historic performance aftermarket manufacturer covering intake manifolds, headers, exhaust, and EFI conversions; much larger scale than Hedman but competes in overlapping LS-swap and classic muscle applications.

Regional players

• Pace Performance: Aftermarket performance parts retailer/distributor that stocks and sells across most of the same brands Hedman serves (including Hedman's competitors) — comparable business model but operates as a multi-brand retailer rather than manufacturer, providing a read on channel demand.
