Kooks Headers Torque Series Stainless Steel Shorty Headers

The Kooks Torque Series Shorty Headers are a purpose-built performance upgrade for street-driven trucks and SUVs seeking real, measurable gains over restrictive factory exhaust manifolds. Engineered as a direct bolt-on replacement for OEM manifolds, the Torque Series is designed to work with factory catalytic converters and retain provisions for factory emissions systems — delivering meaningful power improvements without requiring a tune on most applications.

Key Features:

• T304 Aircraft-Grade Stainless Steel Construction — Fabricated from heavy-duty 16-gauge T304 stainless steel for superior corrosion resistance, high-temperature durability, and long-term reliability
• Stepped Primary Tube Design — Mandrel-bent, stepped primary tubes optimize exhaust gas velocity and scavenging effect across the RPM band for a broader, flatter power curve
• Laser-Cut 3/8" Stainless Steel Flanges with D-Shaped Ports — Precision-cut flanges resist warping under heat cycling, ensuring a leak-free seal at the cylinder head
• Hand-Ground Ports — Each port is individually hand-finished to remove restrictions and maximize smooth exhaust flow out of the cylinder head
• Patented Scavenging Spike Collectors — One-piece collectors feature Kooks' patented scavenging spike design to maximize exhaust velocity and scavenging efficiency
• Factory Catalytic Converter Compatible — Outlet flanges connect directly to OEM catalytic converters and factory exhaust, retaining emissions equipment where applicable
• Complete Hardware Kit Included — Each set ships with all required gaskets, bolts, and installation hardware — no additional parts needed
• No Tune Required — Compatible with factory engine management on most applications, making these an ideal bolt-on upgrade for daily-driven vehicles
• Limited Lifetime Warranty — Backed by Kooks' limited lifetime warranty to the original purchaser, covering defects in materials and workmanship
• Handcrafted in the USA — Manufactured at Kooks' state-of-the-art facility in Statesville, North Carolina
