Since1958, they have been \nproducing high-quality, hand-built, mandrel-bent exhaust headers. Each and \nevery header is tuned with the proper tube size and length to efficiently \nremove all of the exhaust from each cylinder, reducing pumping losses, and \nresulting in dramatic increases in horsepower and torque. Doug's headers \nare carefully developed on the vehicles that they are intended to fit and \nare re-checked numerous times during the design and manufacturing process. \nTheir designs include mid-length headers, Tri-Y headers, and long tube \nheaders, plus manifold replacement headers. \u003cbr\u003e\u003cbr\u003eTheir headers come with all the necessary mounting hardware, collector \nreducers or connector pipes, premium extra-thick gaskets, and detailed \ninstallation instruction sheets. The gaskets are rated up to 1100 degrees \nF, pressures to 3700 psig (255 bar), and are designed for an exact port \nmatch with their headers.\u003cbr\u003e\u003cbr\u003eDoug's Headers offer a choice of finishes:\u003cbr\u003e\u003cbr\u003e* Metallic Ceramic Thermal Barrier Coating (MCTBC), which is polished with \na vibratory finishing process that not only produces a high-luster aluminum \nappearance, but also compresses and activates the coating, which increases \nthe surface hardness. The finish is 60 percent more corrosion resistant \nthan an unpolished surface, easy to maintain, and will last for years under \nnormal operation conditions. MCTBC also protects and extends the life of \nheaders by creating a thermal barrier that significantly lowers under hood \ntemperatures and protects the substrate metal from thermal fatigue.\u003cbr\u003e\u003cbr\u003e* Hi-Temp black coating is an affordably priced alternative to their MCTBC. \nThis finish provides good corrosion and heat protection when compared to \nmany of the \"cheaper\" header finishes being applied by our competitors.\u003cbr\u003e\u003cbr\u003e* Raw steel is available for individual customizing\u003cbr\u003e\u003cbr\u003eUnless otherwise noted, these headers are designed to fit the vehicle as it \ncame from the manufacturer. This includes components like cylinder heads, \nchassis, steering, motor mounts, body mounts and bushings, etc. If your \nvehicle is using aftermarket components, parts from other applications, or \ncustom altered parts, then it is the installer's responsibility to verify \nfitment.\u003cbr\u003e\u003cbr\u003e","brand":"Doug's","offers":[{"title":"Default Title","offer_id":48144094724354,"sku":"DOU-D3321","price":1088.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/b862e3aa90516b0b816714319c0d2083.jpg?v=1784997789","url":"https:\/\/www.lethalperformance.com\/products\/doug-s-long-tube-header-82-92-gm-f-body-265-400-sbc-1-3-4-primary-3-collector-silver-ceramic-coated-d3321-d3321","provider":"Lethal Performance","version":"1.0","type":"link"}
