JBA Headers 1811SJS 1-3/4" Shorty Header Silver Ceramic Stainless Steel

The JBA Performance Exhaust 1811SJS is a 1-3/4" primary tube shorty header set crafted from durable stainless steel and finished in a high-temperature silver ceramic coating for increased corrosion protection and a thermal barrier that helps reduce underhood temperatures. Designed as a direct-fit, bolt-on upgrade, these headers are significantly less restrictive than stock exhaust manifolds, delivering real gains in horsepower, torque, and engine efficiency.

At the heart of the JBA 1811SJS is the proprietary JBA Firecone collector — a race-proven merge collector design engineered to maximize power and torque output across the RPM range. Combined with precision mandrel-bent primary tubes, the scavenging effect is optimized for improved throttle response and exhaust flow.

Key Features:

• 1-3/4" mandrel-bent stainless steel primary tubes — superior flow, long-term durability, and improved throttle response
• Proprietary JBA Firecone collector — race-proven technology for maximum horsepower and torque gains
• Silver ceramic coating — high-temperature finish providing enhanced corrosion resistance and a thermal underhood barrier
• 3/8" thick laser-cut machined flanges — resists warping, prevents exhaust leaks, and simplifies installation
• Extra thick collector domes — will not distort under heat or stress; leak-free design
• Oversized exhaust ports — increased flow capacity; accommodates cylinder head porting
• Factory-style emission connections — retains OEM O2 sensor and emissions hardware for easier installation
• Includes premium hardware and installation instructions — for a professional, no-leak install
• CARB EO Exemption — 50-state legal when installed per manufacturer's application guide and instructions
• Sold as a pair

Built with the same dedication JBA brought to the GTO aftermarket, these G8 shorty headers deliver proven performance gains for street driving, towing, and track use — all backed by JBA's commitment to quality construction.
