Doug Thorley Headers made to fit your C6 Corvette ZO6.

The Tri-Y design yields maximum power from idle to Redline, while adhering to strict emissions standards. Engineered to be well-suited for Trucks, Tow-Rigs, and RV’s, power significantly increases in mid-range RPM’s, making this style exceptionally efficient at highway speeds. Fuel economy and low-end torque increase dramatically with the Tri-Y systems while reduced backpressure, lower engine heat and lessened weight are all added benefits of this design.

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. They apply 3 mils inside the tubing and 5 mils on the outside of the Header.
