Kooks 1-5/8" to 1-3/4" Stepped Long Tube Headers for 2019–2025 Ram 1500 5.7L HEMI
The Kooks 1-5/8" to 1-3/4" stepped long tube headers deliver massive torque gains for 2019–2025 Ram 1500 trucks with the 5.7L HEMI V8, replacing factory manifolds to unlock dyno-proven gains of 40–55 rear-wheel horsepower and 45–60 lb-ft of torque through equal-length primaries, merged collectors, and optimized stepped design for maximum low-end grunt and top-end power in towing or performance applications.
Handcrafted from T304 aircraft-quality stainless steel with 3/8-inch laser-cut flanges and full TIG welds, this header-only system (no EGR or cats) supports over 700 HP while maintaining factory ground clearance and heat shielding for daily-driven trucks. The stepped primaries improve exhaust velocity and reduce backpressure for quicker turbo spool on modified builds or better throttle response in stock applications.
For Ram 1500 owners who demand championship-level performance with proven reliability, the 35201110 stepped headers are the race-winning bolt-on solution trusted by HEMI enthusiasts worldwide.
