Doug Thorley 1 3/4 TRI-Y headers for sale
Doug Thorley 1 3/4 TRI-Y headers for sale
-------------------------------------------------------------------------------- I have changed my headers from 1 3/4 to 1 7/8. These headers have always done well by me. I started off stock, then went NA. After a few years of NA I went supercharged. I race it as well as do half mile runs. I am now looking for the last bit of HP I can get up top. These are great for anyone who is looking to make the jump to Long Tubes and anyone NA or up to 600HP. You can use them for higher HP, but the block could then benefit from larger size. 1 3/4 keeps better torque down low and with tri-y you keep the torque through midrange. Here is a great deal. I bought them at $750 when I ordered them. Looking for 450 plus buyer pays shipping. Why the Tri-Y Why the Tri-Y? Serious Horsepower that’s why! Invented by Doug Thorley Headers, the Tri-Y header is designed to match the synchronization of the engine firing order, thereby maximizing exhaust scavenging. This design creates the optimum torque and greatest horsepower gains in comparison to any other design. See what why many say this is one of the best performance headers out there! Call us to get any question answered. https://youtu.be/imJmyp5HhzY
