{"product_id":"4-2-1-header-with-catalytic-converter","title":"4-2-1 Header with Catalytic Converter","description":"The 1320 Performance Stainless Steel Header is crafted from robust T-304 stainless steel with a brushed finish, ensuring durability and resistance to cracking. Its mandrel-bent construction and TIG welded seams contribute to longevity. The header features a 4-2-1, two-piece design and a high-flow 2.5-inch collector, which is larger than the OEM 2-inch collector, to improve exhaust gas flow.\n\nIt includes an EPA-approved 2.5-inch catalytic converter with flanges for both the header and exhaust. Note that the catalytic converter will require welding by a muffler shop to integrate with your specific exhaust setup.\n\nThis header is designed exclusively for the 1997-2001 Honda Prelude Base model (Non-SH). It is also compatible with pre-1965 classic vehicles that have had an H22A4 engine swapped in.\n\nA crucial installation note: If your vehicle does not have aftermarket solid motor mounts, do not connect the 2-bolt bracket on the down-pipe to the engine block. Using this bracket with OEM motor mounts can lead to bracket weld breakage due to excessive engine movement.","brand":"1320 Performance","offers":[{"title":"Default Title","offer_id":52686648115512,"sku":"1320-bb6-HD-2.5-base","price":395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658756472.webp?v=1784875632","url":"https:\/\/store.motormia.co\/products\/4-2-1-header-with-catalytic-converter","provider":"MOTORMIA","version":"1.0","type":"link"}
