Shortie Headers by Doug Thorley

Doug Thorley's award winning line of Shortie Headers are designed with ease of installation in mind. Many late model applications do not allow use of a Tri-Y or Long Tube header because of emissions compliance standards. In those cases, our Shortie design is utilized in all RPM ranges for maximum performance while maintaining EO compliance and approval.

• Safe - 50 stage legal
• Strong - 3/8" flanges and 14 gauge tubing
• Reliable - maximum torque and power gains
• Awesome - easy installation

Headers are available with one of two coatings: Chrome, or Ceramic.

Chrome Finish:
Our Chrome headers are designed to prohibit initial rust or corrosion, but not for extended life. It is not intended to be “show chrome”, as it will discolor upon initial fire-ups, and this is normal. Chrome headers are still guaranteed against manufacturer’s defects and workmanship.

Ceramic Finish:
Doug Thorley’s Ceramic-Thermal coating protects your header against the elements and can take temperatures up to 1,400 degrees F. This coating keeps heat inside the tubing, thus promoting velocity while absorbing up to 40% of the engine temperature. This keeps your engine running cooler and helps in all areas where heat is the enemy. 3 mils is applied inside the tubing and 5 mils on the outside of the Header.
