JBA Cat4Ward 1-5/8 in. Raw 409SS Shorty Headers for Select 2014-2020 GM Trucks & SUVs (5.3L / 6.2L) 1850S-4

Fits select 2014-2020 Chevrolet Silverado/Suburban/Tahoe, GMC Sierra/Yukon/Yukon XL, and Cadillac Escalade (5.3L / 6.2L).

JBA Cat4Ward shorty headers (MPN: 1850S-4) are engineered as a high-performance replacement for restrictive factory cast-iron exhaust manifolds. Constructed from mandrel-bent 409 stainless steel tubing, these headers improve exhaust scavenging and engine efficiency, providing a significant upgrade for towing, off-roading, or daily driving.

Each header features JBA’s proprietary Firecone® collector, which utilizes a race-proven design to merge exhaust pulses and maximize torque output where you need it most. The 3/8-inch thick machined flanges feature oversized exhaust ports to ensure a secure, leak-free seal at the cylinder head, while integrated factory-style emission connections allow for a direct-fit installation that maintains original system architecture.
