The raw aluminized steel Aero Chamber is designed to do much more than simply muffle exhaust noise. The Aero Chamber Muffler produces a deep throaty powerful sound that will not change with time. The Hooker Aero Chamber uses a unique step principal, similar to that which is currently popular in racing header design. The aerodynamically designed chambers flow 23% better and produce more horsepower and torque than the most popular high performance brand.

Product Features:

• Feature intricate stainless steel, robotic weld seams
• Stepped acceleration Chamber Increases Exhaust Gas Velocity and Maximum Flow
• Resonance Chamber and Tuning Tube Cancels Unwanted Frequencies and Amplitudes (No annoying tin can sound or drone at cruising speed)
• Sound Absorption Chamber eliminates High Frequency Sound Waves for Deep Throaty Powerful Sound
• Aerodynamic Lens Directs Sound Pressure Waves into Acceleration Chamber and Out of Muffler
• Stainless Steel Perforated Internal Plate Eliminates Internal Rust
• Reinforced Inlets and Outlets
• 4-3/4″H x 10-1/4″W x 14″L 16 Gauge Raw Aluminized Steel Case
• Single 2-1/4″ Center Outlet
• Single 2-1/4″ Offset Inlet
• Three Internal Bulk Heads for Superior Case Durability and Stability

Flow tech headers are the perfect combination of performance and value. Flow tech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16″ flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces under hood temps for increased performance.

Product Features:

• Tuned-length primary tubes for better performance
• Mandrel-bent tubing for smooth exhaust flow
• Light weight & sturdy 16 gauge tubing
• Mandrel-formed Power Plenum collector for low back pressure
• Sturdy, leak-tested O-Ring port seals
• Engineered for a precision fit
• Designed for easy, trouble-free installation
• Includes all mounting hardware and premium gaskets
• Shorty style header, will also work on catalytic converter equipped vehicles. Head pipe fabrication required

FLOWTECH’s Afterburner Turbo Chamber Headers represent the first new major design change in exhaust technology in decades. This designs combines the race-proven 4 into 1 design with the torque managing capabilities of a Tri-Y header. The turbo chamber helps smooth out exhaust turbulence for increased performance and a broad power curve.

Product Features:

• Painted versions feature a premium high-temperature black finish
• Horsepower and Torque increased over conventional header design
• Big 3″ secondary collector for reduced back pressure
• Tuned-length primary tubes combine with Velocity Tube to smooth out exhaust pulses
• Patented Velocity Tube increases cylinder scavenging
• All hardware and premium gaskets included for a complete installation
• Smooth Exhaust Pulses

Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer, Hooker Competition headers offer premium features at a very competitive price. Made of durable 304 stainless steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16″ machined flanges. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available.
