Doug's Headers has long been recognized of as one of the premiere exhaust header manufacturers in the performance industry. Since1958, Doug's Headers has been producing high-quality, hand-built, mandrel-bent exhaust headers. Every Doug's header is tuned with the proper tube size and length to efficiently remove all of the exhaust from each cylinder, reducing pumping losses, and resulting in dramatic increases in horsepower and torque. Doug's headers are carefully developed on the vehicles that they are intended to fit and are re-checked numerous times during the design and manufacturing process. Doug's Headers is not only famous for a wide selection of musclecar headers, but also for CARB-approved applications for motor homes and popular late model trucks and SUVs. Premium gaskets with bolts and connectors are supplied with each header. Doug's Headers are available in your choice of a metallic ceramic thermal-barrier coating, for optimum protection and appearance, or a bare finish. 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.

High quality

Summit RacingSummit Racing Verified Purchase

These headers are great! Very good finish and quality. Fit is very tight to the front frame on right side. You will not be able to leave the transmission cooler lines and bracket in there factory locations. You may also need to shim up the right motor mount . I wish someone would have told me that it would have saved a lot of time.
