{"product_id":"expreme-4-2-1-exhaust-manifold","title":"EXPREME 4-2-1 Exhaust Manifold","description":"The Tomei EXPREME exhaust manifold, part number TB6010-SB02B, is engineered for Subaru EJ25 and EJ20 single scroll engines, specifically for the Subaru WRX and WRX STI models. This system utilizes a 4-2-1 isometric design, meticulously crafted to maximize performance gains at high RPMs by optimizing exhaust pressure control and flow.\n\nConstructed from durable SUS304 stainless steel with a 2.5mm pipe thickness, the manifold features a lost wax collector. This manufacturing process enhances exhaust gas flow by eliminating internal welds and preventing stress-related cracking. The equal-length piping, with diameters of φ42.7mm, φ45.0mm, and φ60.0mm, is designed to extract the absolute maximum potential from your engine's turbine.\n\nThe kit comes complete with the exhaust manifold, turbine support pipe, a titan exhaust bandage, bandage band, gaskets, bolts, and bolt smooth paste. The product's design results in a distinct, higher-pitched racing sound. It offers a significant weight reduction compared to the OEM part, weighing 8.85 kg versus the OEM's 13.9 kg.\n\nThis exhaust manifold is compatible with Subaru WRX models from 2002-2014 and Subaru WRX STI models from 2004-2021. Fitment also extends to Subaru Forester XT models from 2004-2013. Installation may require professional expertise and specialized tools, and it is important to note that modifications for performance may not meet legal requirements for public road use.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52689414357304,"sku":"TOMTB6010-SB02B","price":890.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687729755.jpg?v=1784906409","url":"https:\/\/store.motormia.co\/products\/expreme-4-2-1-exhaust-manifold","provider":"MOTORMIA","version":"1.0","type":"link"}
