Product Details

Steel Silver Ceramic Coated Long Tube 4 To 1 Exhaust Headers with Adapters by Doug Thorley Headers®. Primary Tubing Diameter: 1.75". Collector Outlet Diameter: 3". Color: Silver. Header Coating: Ceramic. Header Style: Long Tube. Backed by over 50 years of knowledge and experience, Doug's headers are designed to outflow your stock exhaust manifolds by leaps and bounds. These headers will give your engine more horsepower and torque across the entire RPM range, no doubt about it! To make these headers last, Doug's made them out of industry leading 14-gauge mild steel tubing with 3/8" thick flanges. Topping all of that off, all of Doug's headers come beautifully ceramic coated to greatly reduce under-hood temperatures and protect the headers from the environment. All of this 100% American made, and backed by Doug's 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. Doug's headers are designed to outflow your stock exhaust manifolds by leaps and bounds. Their headers 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.
