Modern engine compartments are crowded spaces, and seem to be getting even more crowded with every new year. That's why we've developed Doug's Shortie Headers to provide maximum performance in a compact, easy to install package. Doug's Shortie Headers replace restrictive stock manifolds with thick wall steel tubing for increased exhaust flow, but retain the factory mounting locations for emissions equipment to keep you street legal.

The Shortie Header works great in applications where space is limited, and a Long Tube or Tri-Y header just won't fit. Easy installation, more power and better fuel economy make the Shortie a winner.

For over 50 years, Doug Thorley Headers has been an innovator in the automotive aftermarket. Driven by a passion for performance and superior quality, they are committed to developing 100% American-made products that will reliably deliver maximum horsepower and torque. Doug Thorley Headers® has been pushing the limits of automotive technology since they first invented the Tri-Y header in 1958, and they do it all on American soil.
