{"product_id":"lhd-4-1-stepped-medusa-headers","title":"LHD 4-1 Stepped Medusa Headers","description":"The Evolve LHD 4-1 Stepped Medusa Manifolds are performance exhaust headers specifically designed for Left Hand Drive BMW E39 M5 models equipped with the S62 V8 engine. The factory exhaust manifolds are identified as a significant restriction, and upgrading them is crucial for any meaningful power gain from the exhaust system.\n\nConstructed from T304 Stainless Steel in Italy, these headers feature a 4-1 stepped design. This design is engineered to optimize the power band across all RPMs, enhancing the S62 engine's inherent strong torque from 2000-5000rpm while also increasing power above 5000rpm by an estimated 25-40hp. The manufacturer claims a minimum gain of 30 hp and 27 lb\/ft of torque when used independently, with potential to reach 445 bhp \/ 400+ lb\/ft when combined with Evolve software and intake systems.\n\nIt is essential that these headers are used in conjunction with Evolve Sports Cats or De-Cats. The engine will produce a slightly more purposeful note, with noise levels only marginally increased when using the headers alone.\n\nNote: This product is for Left Hand Drive vehicles only.","brand":"Evolve Automotive","offers":[{"title":"Default Title","offer_id":52687979217208,"sku":"EVO-S62-MANI-LHD\/EVO-S62-MANI-DC","price":4419.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664197304.webp?v=1784888454","url":"https:\/\/store.motormia.co\/products\/lhd-4-1-stepped-medusa-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
