This direct-fit component is engineered with an interference 4-2-1 design to optimize exhaust scavenging, leading to improved throttle response and overall performance suitable for daily driving and street performance upgrades.\n\nThey feature precision-machined flanges to ensure a reliable, leak-free seal, and smooth merge collectors for efficient flow. The primary pipes measure 38mm, the secondary pipe is 45mm, and the outlet is a 51mm flange. A heat-resistant paint finish, rated to 600°C, provides lasting protection against high temperatures.\n\nFitment notes indicate that while these are direct-fit headers, clearance may vary depending on engine mounts, steering components, and other aftermarket parts. It is recommended to check availability before ordering and to protect painted surfaces and wrap the headers during trial fitting. A replacement gasket (RBG253) is sold separately and recommended for installation.\n\nThese headers are backed by Wildcat Headers with a 2-year warranty, subject to standard terms. It is crucial to check local emissions and roadworthiness regulations before proceeding with installation.","brand":"Wildcat Headers","offers":[{"title":"Default Title","offer_id":52664130863416,"sku":"WILD704-1","price":531.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687541499.webp?v=1784333736","url":"https:\/\/store.motormia.co\/products\/wild704-4-2-1-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
