Are you tired of dragging your long tube headers on the ground every time your lowered car hits a bump? If so, then these headers are for you! Just a little shorter than true long tube headers, we designed these to give you the maximum in performance while keeping them short enough to not smack the ground when the road gets a little bumpy. Of course, the shorter design makes for a bit easier of an install than long tubes also, you definitely don't need to be lowered to run these. To make these headers last, we made them out of industry leading 14-gauge 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 of this 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.
