JBA Short Tube "Shorty" Headers

Please note: We do not sell short tube headers.

At the heart of your GM Truck or SUV is a dependable and powerful 8.1L Vortec 8100 engine. These big blocks are heavily restricted by the factory cast manifolds and your performance and efficiency suffers as a result. JBA's Shorty Headers designed to open up the breathing on your truck with high-flowing mandrel-bent 1-3/4" primary tube that merge into JBA's patented Firecone® collector. By reducing back pressure and turbulence in the exhaust, the JBA headers free up torque, horsepower and efficiency. Gains of 20 rear wheel horsepower and 35 lb-ft of rear wheel torque are common. These headers also feature ultra thick 3/8" laser-cut flanges and are available in a variety of finishes to fit your specific needs. Each shorty header kit includes high quality hardware and thorough instructions for a easy installation process.

Stock Manifolds Are Restrictive

Stock exhaust manifolds reduce exhaust flow, reducing power and economy. Headers promote better scavenging, improving exhaust flow, increasing efficiency and power output. Our performance kits increase your engine's ability to breathe and will show maximum gains when coupled with free flowing shorty headers.

Smog Legal Performance

Want big power but still have to pass smog? JBA shorty headers are 50 state legal and still offer 70% of the gains seen from long tube headers.

Hot Rods & Muscle Cars

Shorty headers are also a great solution for hot rods and muscle cars looking to complete an engine swap as they fill the same space as the stock manifolds.

Ceramic Coated Header Benefits

Long-lasting ceramic coatings are a thermal barrier that reduces the heat radiated from the headers, keeping underhood temperatures down. They are highly resistant to petroleum products, scratches, extreme heat and inclement weather.

What Is A FireCone Collector?

Abrupt changes in exhaust manifold volume, such as the transition from primary tube to collector, causes turbulence and a drop in exhaust gas velocity. Turbulence causes restriction, reducing header air flow. The JBA Firecone merge collector eases the transition helping to maintain the direction and speed of the exhaust flow. The result is a noticeable increase in power and efficiency via improved scavenging.

"Header-Proof" Ceramic Spark Plugs

Ceramic Spark Plug Wires - $350

8.1L engines with short and long tube headers routinely melt stock plug wires and even performance spark plug boots. Ceramic spark plug wires eliminate burnt spark plug boots in boats, trucks, hot rods and RVs. If you've had this problem before or don't want to worry about it in the future, check out our 45 degree ceramic plug boots which are rated to withstand extreme temperatures up to 2000°F!
