It was the late 1950s, during the golden era of hot rods, when Doug Thorley crafted his plans for the highest quality headers on the block. Fine tuning, superior craftsmanship and unmatched attention to detail helped Doug Thorley Headers power street racers everywhere.
Now 50 years later, Doug Thorley Headers are built with the same mission in mind: amping-up the power of your street ride. Thorley Headers use one of three souped-up designs: a unique Tri-Y setup that roars from idle up to 4500 RPM; shortie headers for ease of installation and smog compliance; and long tube headers that specialize in mid to high RPM power.
Because they're setup for the streets, Thorley Headers also feature the hardware and custom flanging to be 50-state smog legal (some shortie applications). Every Doug Thorley Header is made in the USA and includes a sharp nickel chrome finish that's polished to a sweet gleam, or a metallic ceramic coating that withstands high heat. And, your Doug Thorley Headers carry a Lifetime Warranty for the original owner.
Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts.
