This header is designed as a direct bolt-on application for both 2-door coupe and 4-door chassis, ensuring a straightforward installation. Its construction utilizes 44mm primaries that smoothly transition into 50mm secondaries, optimizing exhaust gas flow. The design also prioritizes fitment past the subframe and sway bar, providing ample clearance for engine movement.","brand":"Ktuned","offers":[{"title":"Default Title","offer_id":52686526349624,"sku":"KBH-CSI-K20","price":449.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/659228822.webp?v=1784874604","url":"https:\/\/store.motormia.co\/products\/k-tuned-civic-si-header","provider":"MOTORMIA","version":"1.0","type":"link"}
