{"product_id":"stepped-primary-tube-headers","title":"Stepped Primary Tube Headers","description":"The Dynatech MuscleMaxx Header Systems are engineered as a direct bolt-on upgrade for specific Small-Block Chevy applications, eliminating the need for modifications. These full-length headers are constructed from durable steel with a silver ceramic coating for enhanced longevity and aesthetics. They feature substantial 3\/8-inch laser-cut flanges designed to ensure a leak-free seal, crucial for optimal performance.\n\nThe primary tubes are stepped, ranging from 1-3\/4 inches to 1-7\/8 inches in diameter, combined with a long tube design to maximize horsepower and torque gains. The header ports are specifically sized to offer optimized flow, accommodating a wide array of cylinder heads, including popular Crate Engine options. For installation, these systems include headers, reducers, gaskets, bolts, and hardware, with 4-bolt, 3-inch collectors and included 3-inch reducers.\n\nThis particular system is designed to fit 1967-69 Camaros and 1968-74 Novas equipped with Small-Block Chevy engines. The low-profile collector connections are intended to provide maximum ground clearance during operation.","brand":"Dynatech","offers":[{"title":"Default Title","offer_id":52687869542712,"sku":"74021310","price":629.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663681718.jpg?v=1784886982","url":"https:\/\/store.motormia.co\/products\/stepped-primary-tube-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
