Kooks Headers

<h3>A Legacy Forged in Fire: The Kooks Headers Story</h3><p>Few brands in the performance aftermarket carry the kind of hard-earned credibility that <strong>Kooks Headers &amp; Exhaust</strong> has built over more than six decades. The story began in 1962, when founder George Kook — known to the racing world as &quot;Papa Kook&quot; — used a blowtorch to craft his very first set of headers for his family&apos;s race car. That hands-on, race-first mentality never left the company. Through three generations of family leadership, all Kooks products have continued to be crafted in the U.S., with the company remaining independently owned and managed.</p><h3>Pioneers of the Stainless Steel Header Revolution</h3><p>Kooks prides itself on being a pioneer of the stainless steel header revolution and an innovator in the exhaust industry — designing, testing, and manufacturing first, with other companies following their lead. Today, every header leaves their Statesville, North Carolina facility manufactured in the USA, ISO 9001:2015 certified, and backed by a limited lifetime warranty.</p><p>What truly sets Kooks apart is the breadth of their capabilities. Kooks stands as the sole header company capable of offering headers for gas engine trucks while simultaneously crafting bespoke race headers for applications exceeding 3,000 horsepower. Whether you are building a weekend drag car or a street-driven daily, there is a Kooks solution engineered to fit.</p><h3>Race-Proven Across Every Discipline</h3><p>Over six decades later, Kooks remains dedicated to producing top-tier race headers and exhaust systems, playing a pivotal role across drag racing, circle track competitions, road racing, motorcycle events, and even offshore boat races. Vehicles equipped with Kooks headers have won hundreds of championships and broken countless records across organizations including the NMCA, NHRA, SCCA, NASCAR, and NMRA.</p><h3>Built from the Best Materials</h3><p>Kooks&apos; commitment to quality starts with the materials. Kooks exhaust systems are crafted from 304L stainless steel, 16-gauge tubing for unmatched strength and longevity — a premium material that resists corrosion, delivers consistent performance, and handles the heat and stress of high-performance driving. Products are crafted from high-quality, aircraft-grade stainless steel for unmatched reliability, and every item is certified to ISO 9001:2015 standards and backed by a limited lifetime warranty.</p><h3>The Complete Exhaust Lineup</h3><p>Kooks offers a comprehensive range of exhaust components to cover every stage of your build. Their signature <a href="/3181-kooks-headers-exhaust-header-5848">exhaust headers</a> are the cornerstone of the brand — available in Super Street Series, Long Tube, and Torque Series configurations, covering Corvette, Camaro, Mustang, RAM, GM Truck, Cadillac, Chrysler, Pontiac, and Ford applications with vehicle-specific precision. For enthusiasts looking for a complete solution, Kooks <a href="/3181-kooks-headers-exhaust-system-kit-10727">exhaust system kits</a> bundle headers with the matching downstream components, eliminating guesswork. Kooks cat-backs are stainless, mandrel-bent, and tuned for aggressive sound without excessive drone.</p><p>Connecting those systems are precisely engineered <a href="/3181-kooks-headers-exhaust-pipe-10038">exhaust pipes</a> and <a href="/3181-kooks-headers-exhaust-crossover-pipe-16090">exhaust crossover pipes</a>. Pairing headers with the right mid-pipe is where Kooks shines, offering catted and off-road setups with X-, H-, and Y-pipe designs depending on your platform. Kooks&apos; complete line of exhaust components includes headers, header collectors, exhaust tubing, and mufflers for GM, Ford, Dodge, and specialty race applications.</p><p>From a single gas torch in 1962 to a full-scale, ISO-certified manufacturing facility, Kooks Headers &amp; Exhaust has earned its place as one of the most trusted names in American performance. If maximum exhaust flow, race-proven fitment, and made-in-the-USA quality matter to your build, Kooks delivers on every count.</p>

Product Details

The Kooks Headers 22603400 is a pair of 3-inch high-output stainless steel catted connection pipes designed to bridge Kooks long tube headers to the factory exhaust system.

Key Features:

  • Pipe Size: 3 in. x 2-3/4 in. OEM high-output connection pipes
  • Catalysts: H.O. GREEN high-output catalytic converters for improved flow and emissions compliance
  • Connections: Torca SwivelSeal OEM-style connections for a secure, leak-free fit
  • Material: Premium stainless steel construction for long-lasting corrosion resistance and heat durability
  • Handcrafted in the USA by a family-owned manufacturer with over 60 years of racing heritage

Kooks Headers and Exhaust has been a leader in high-performance exhaust manufacturing since 1962, earning championships across NHRA, IHRA, NMCA, NMRA, NASCAR, NASA, SCCA, and more.
