{"product_id":"4-2-1-stainless-header","title":"4-2-1 Stainless Header","description":"The J's Racing Stainless Header is a meticulously crafted 4-2-1 exhaust manifold engineered to enhance the performance of Honda S2000 AP1 and AP2 models equipped with F20C and F22C1 engines. This header features a lightweight SUS304 stainless steel construction, with material thickness ranging from 1.2mm to 1.5mm. Weighing in at 5.6kg, it offers a significant weight reduction of 4.9kg compared to the stock header's 10.5kg.\n\nThe 4-2-1 design is optimized to increase both torque and horsepower across all rev ranges, thereby maximizing the engine's potential. A key feature is the integrated fitting hole for an air\/fuel ratio sensor, which is invaluable for fine-tuning the engine's performance.\n\nInstallation requires careful attention to detail, including applying the correct tightening torque. The manufacturer notes that over time, vibration from deteriorated engine mounts may lead to cracks in the welded areas, and recommends consulting a local shop for any necessary repairs. It is important to confirm current availability directly with the vendor before placing an order.","brand":"J's Racing","offers":[{"title":"Default Title","offer_id":52662786163000,"sku":"XA-S1","price":1877.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687497908.jpg?v=1784320975","url":"https:\/\/store.motormia.co\/products\/4-2-1-stainless-header","provider":"MOTORMIA","version":"1.0","type":"link"}
