Scavenge that Exhaust Gas Better with Dynatech Drag Race Headers

Dynatech earned its chops making drag race headers that really scavenge exhaust gas out of your engine’s combustion chambers so the incoming air and fuel can enter, ignite, and make glorious horsepower. Whatever you race—dragster or doorslammer, stock or strut suspension, even Mustangs with GM motors—Summit Racing has Dynatech headers for it.

Dynatech models key interference and mounting points under the hood and around the chassis so engineers can plot header tube routing, tube length, and diameter for the best fit and function. That means you get headers that work better with a minimum of fitment issues.

Dynatech Drag Racing Headers are made from 16-gauge steel and have thick CNC laser-cut and surfaced flanges for a virtually leakproof seal.

Downsweep and Pro Stock Headers for Big Chevy
Have a big block Chevy in your drag car? Dynatech Downsweep and Pro Stock headers have 3/8 inch thick flanges with raised ports for improved flow. Their downswept design gives exhaust gases a straight shot out of the cylinder head exhaust ports into the equal-length primaries. Exhaust gases travel several inches into the headers before hitting any bend, which boosts exhaust flow. Other features include port gussets to eliminate cracking and jig-located mounting tabs for the collectors.

Summit Racing also carries Dynatech’s High Velocity Merge Collectors to go with your new headers. The four into one collectors are 12 inches long and feature the optimum reduction angle to increase torque output and add 5 to 10 extra horsepower.

Available Primary Tube Sizes
• 2.25 inch, standard port spacing, for strut-style cars, ceramic-coated
• 2.25 to 2.375 inch stepped, standard port spacing, ceramic-coated or chrome
• 2.375 to 2.5 inch stepped, standard port spacing, ceramic-coated or chrome

Dynatech Engine Swap Headers are designed to fit a small block or big block Chevy, GM LS, or 351 Windsor into 1979-2004 Mustangs with AFCO, AJE, and other tubular K-member. The long-tube headers allow you to use the transmission of your choice, provide excellent ground clearance, and can be hooked up to a full exhaust system.
