{"product_id":"ram-4-2-1-long-tube-304-stainless-steel-header","title":"Ram 4-2-1 Long Tube 304 Stainless Steel Header","description":"The K-Tuned Ram Header is a performance exhaust manifold engineered specifically for K-swapped Honda and Acura vehicles. By using a long-tube design that tucks upward into the engine bay, this component significantly improves ground clearance and provides ample clearance for shifter boxes. The unit features 304 stainless steel construction with equal-length tubing and a proven 4-2-1 stepped design, utilizing 44mm, 47mm, and 50mm primary diameters that culminate in a 2.5-inch exit. Three true merge collectors are integrated at all transitions to streamline exhaust flow and maximize both mid-range and high-end power.\n\nThis header is compatible with K20 and K24 engines installed in the following chassis: 1990-1993 Acura Integra (DA), 1992-1995 Honda Civic (EG), 1996-2000 Honda Civic (EK), and 1994-2001 Acura Integra (DC2). Please note several critical fitment exclusions: this product does not fit any Right-Hand Drive (RHD) vehicles, and it is not compatible with the EF chassis.\n\nDesigned for enthusiasts seeking top-tier performance in K-swapped builds, this header has demonstrated superior power output in dyno testing compared to standard 4-2-1 swap headers and 4-1 race headers. Proper installation is recommended to ensure the geometry of the tube turns remains effective in maintaining exhaust gas temperature and velocity.","brand":"K-Tuned","offers":[{"title":"Default Title","offer_id":52664211636536,"sku":"KTH-RAM-421","price":209.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687546172.jpg?v=1784335226","url":"https:\/\/store.motormia.co\/products\/ram-4-2-1-long-tube-304-stainless-steel-header","provider":"MOTORMIA","version":"1.0","type":"link"}
