Patriot Tight Tuck Headers

Patriot Tight Tuck headers provide the solution to many problems associated with engine swaps in modern street rods. They fit in the tightest of engine compartments, and they clear most stock motor mounts. Many Tight Tucks are manufactured from durable 16-gauge tubing and come complete with gaskets, header bolts, and collector reducers. Besides their popular finishes, Patriot also offers a chrome option that is polished before and after assembly for show-quality appearance, as well as a stainless steel option. Order the model designed for your vehicle and engine application. Patriot Tight Tuck finishes: * Metallic Ceramic Thermal Barrier Coating (MCTBC), which is polished with a vibratory finishing process that not only produces a high-luster aluminum appearance, but also compresses and activates the coating, which increases the surface hardness. The finish is 60 percent more corrosion-resistant than an unpolished surface, easy to maintain, and will last for years under normal operation conditions. MCTBC also protects and extends the life of headers by creating a thermal barrier (heat-resistant up to 1,600 degrees F) that significantly lowers underhood temperatures and protects the substrate metal from thermal fatigue. * Hi-Temp black coating is an affordably priced alternative to their MCTBC. This finish provides good corrosion and heat protection when compared to many of the "cheaper" header finishes being applied by our competitors. * Raw steel is available for individual customizing 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.
