Exhaust systems and headers — superior power and efficiency.

For more than 20 years, Dynatech has focused on new technology to continue producing exhaust systems with superior fit, function and performance. Racing and engineering advances throughout the industry are bringing a new breed of racing and performance cars to the tracks and the streets. You will see that excitement and new performance technology when you look at Dynatech exhaust products.

Drag racing, circle track, street rod & muscle, and high performance.

Regardless of your racing or performance preference, Dynatech’s virtual reality design systems capture key interference and mounting points under the hood and throughout a car or truck chassis. Tube lengths, diameters and routing can all be designed and manipulated for the perfect fit and increased performance. These precision design systems not only cut design time, but also help create more efficient and more powerful products. All our headers and exhaust systems are tested on dyno equipment to make sure we’re delivering the most horsepower and torque gains for the investment.
