{"product_id":"t304-stainless-steel-long-tube-headers","title":"T304 Stainless Steel Long Tube Headers","description":"The Flashark long tube headers are a performance upgrade for BMW N52 engines, engineered to replace restrictive stock exhaust manifolds. These headers are constructed from premium T304 stainless steel, ensuring durability and corrosion resistance, and feature a mirror-polished finish.\n\nBy upgrading from stock manifolds, these long tube headers unlock more efficient exhaust flow, which translates into smoother power delivery and improved throttle response. The product is designed to add an estimated 8–20 horsepower and enhance the exhaust note with a more aggressive, sporty tone. The headers maintain compatibility with factory oxygen sensors and catalytic converter placements, simplifying emissions compliance where applicable.\n\nFitment is specifically verified for BMW N52 engines in the E90, E91, E92, E93, and E82 platforms. Verified models include the 325i\/325xi\/328i\/328xi\/330i\/330xi (2006-2011) in Sedan and Wagon chassis, the 325i\/328i\/330i Coupe (2007-2012), the 328i Convertible (2007-2012+), and the 128i Coupe (2008-2012).\n\nCritical fitment rules must be observed: these headers WILL NOT FIT non-N52 engine configurations, all right-hand drive (RHD) vehicles, or engine-swapped or heavily modified vehicles. Installation is described as straightforward with pre-drilled mounting points and included hardware, though professional installation is recommended.","brand":"Flashshark","offers":[{"title":"Default Title","offer_id":52688375677240,"sku":"FLES08375","price":229.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663174061.webp?v=1784889291","url":"https:\/\/store.motormia.co\/products\/t304-stainless-steel-long-tube-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
