JBA 4-2-1 Headers for Corvette Z06

JBA Performance Exhaust, a PerTronix Performance Brand, has just introduced this New 4 into 2 into 1 Stainless Steel Header for the 2006-2012 Corvette Z06.

The 6821S headers are built with 3/8” thick flanges at the cylinder head and V-Band collectors for Maximum Power and optimum ground clearance. The 4-2-1 tube design is made from 16 gauge Stainless Steel tubing for durability with 1 7/8” primaries, they merge into 2 1/8” secondary’s and then 3” collectors for increased horsepower and torque throughout the power band. This is not the typical Tri Y type header that has been around for many years, but rather the state of the art exhaust design that is now being used in many forms of racing, including NASCAR. The design accommodates both automatic and manual transmission cars with power brakes, power steering and air conditioning.

The 4 -2 -1 design was developed using independent Dyno Testing at Performance Associates in San Dimas, CA. Their Mustang Chassis dyno is state of the art and allowed the JBA designers to take the 2006 development Z06 from stock rear wheel Horsepower of 377 to a tuned Rear Wheel Horsepower with the JBA 4-2-1 of 440, a real world increase of 63 Rear Wheel Horse Power! Similarly, Torque increased from a stock reading of 350 lbs/ft to 412.

They come in Natural Stainless as well as Bright Silver Ceramic Coating (as shown here) or Titanium Metallic Ceramic coated for a rich appearance and long life. The Metallic Ceramic Thermal Heat Barrier Coatings will decrease under hood temperatures while retaining more heat in the headers for increased flow, these two features add up to more horsepower. These headers come complete with reducers, 11,00o-degree F rated gaskets and premium installation hardware. 

Features:

  • Built with 3/8” thick flanges at the cylinder head and V-Band collectors for maximum power and optimum ground clearance
  • Made from 16 gauge stainless steel tubing for durability with 1 7/8” primaries
  • Comes in Natural Stainless, Bright Silver Ceramic Coating, or Titanium Metallic Ceramic coated for a rich appearance and long life
