50 State Legal Bolt-On Horsepower!
The Hooker Headers Street Force Cat-Back Exhaust Systems are manufactured using 16-gauge aluminized steel tubing that is mandrel bent which increases volume and horsepower while reducing backpressure by maintaining a consistent inside diameter, unlike press bending which crushes or pinches the pipe closed reducing volume by as much as 10%!  These systems are designed to install behind the converter and all other applicable emission control devices using flanged construction (where applicable) and existing stock hangers for easy installation!

Features:

• Exit At Stock Locations
• Mandrel Bent Not Press Bent
• Consistent Inside Diameter
• Maximum Flow
• Uses Existing Stock Hangers
• Large Diameter 16 Ga. Aluminum Tubing
• Low Back Pressure and Long Life

Notes:

• This system is designed to accommodate the factory supplied catalytic converter.
• A pipe is supplied with kit that can be used to replace the catalytic converter on racing vehicles using leaded fuel to prevent damage to the catalytic converter. It is illegal, except for racing vehicles, which may never be driven on the highway, to remove the catalytic converter.
• Hooker Headers designed this kit, in conjunction with Hooker Aero Chamber Series (Qty 2 required, not included) 21502HKR-0 that will bolt to the factory four bolt catalytic converter outlet flange. Extensive dyno track and flow testing has allowed Hooker Headers to produce the finest turbo muffler available.
• Pipes exit behind tires in stock location for Buick Grand Nationals. Tips do not conform to the stock exit location for Monte Carlos.
