    Description

    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.  Details

    Hard to install

    As the title says they are hard to install partly because of weak instructions. My biggest issue with the headers is the y pipe did not fit my stock exhaust. Had to go to exhaust shop for them to put in the stock connector which cost another $60. Good stuff but you'd better have lots of tools, patients, time and an exhaust shop handy to get these in with any ease. That being said Ive noticed good power increase and they make the truck sound perfect with stock catback!

    Awesome pipes

    This is a great sounding set of pipes, and great looking. Also a big power and performance gain. Great deal!

    Headers, the only way to go.

    I have been looking for a set of headers for my car for sometime now. The Doug Thorley headers look great, sound mean, the price was right but they were a real chore to install. I would buy them again.

    Sweet!

    While it wasn't the easiest to install, it was sure worth it. I do recommend buying new studs as well as crush gaskets for the piping after the header. Sounds great, gave the performance and flow I was looking for, and look badass!

    These headers are awesome. Definitely not the thin lightweight bargain basement pieces that will melt your plug wires and be rotted out in a few years. The flanges are very heavy and they use OEM type donuts with steel inserts at the collectors. Definitely well worth the extra cost and by far the best price was here at Auto Anything
