1961-66 Chevrolet C10 Truck / Suburban, Long Tube Tri-Y Doug Thorley Headers

What better way to enhanceyour vehicle than a beautiful set of long tube tri-y headers that will ensure you’re getting the most power possible out of your small block motor! Tri-Y (or 4 into 2 into 1) style headers by design will increase the power of your motor across the widest RPM band possible. That is the beauty of the design, and that is why they are the best street header available. To make these headers last, we built them using industry leading 14-gauge steel tubing with 3/8″ thick flanges. Topping all of that off, our headers come beautifully ceramic coated to greatly reduce under-hood temperatures and protect the headers from the environment.All 100% American made, and backed by our lifetime warranty.
