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 mild steel tubing with 3/8" thick flanges. Topping all of that off, all of our headers come beautifully ceramic coated to greatly reduce under-hood temperatures and protect them from the environment. All 100% American made, and backed by our lifetime warranty of course!
Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.
