{"product_id":"304-stainless-steel-equal-length-exhaust-headers","title":"304 Stainless Steel Equal Length Exhaust Headers","description":"These headers feature an equal length tubing design and a merged collector, which Agency Power states can improve turbo spool by up to 300rpm. Testing on an upgraded turbo vehicle showed gains of up to 30 ft-lb of torque and 20 wheel horsepower on a Mustang Dyno. The free-flowing design also contributes to gains across the entire RPM range.\n\nConstructed from polished 304 stainless steel, these headers boast CNC-machined 0.5-inch thick flanges for durability and a precise fit. They are designed to be a direct bolt-on installation for many Subaru turbo models, including the Subaru WRX (2008-2014), Subaru STI (2004-2016), Subaru Legacy GT (2005-2009), and Subaru Forester XT (2009-2013). However, specific modifications may be required for certain model years. For 2002-2005 WRX models, an oil pan with a header cutout and an oil pickup tube are necessary. 2006-2007 WRX models will require the 02-04 oil cooler assembly and oil feed pipe.\n\nDue to the equal length design, these headers will alter the characteristic Subaru engine sound, resulting in a smoother exhaust note. The improved exhaust flow and quicker turbo spool can also lead to better acceleration times at the drag strip.","brand":"Agency Power","offers":[{"title":"Default Title","offer_id":52686854029624,"sku":"AP-GDA-176","price":700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662147489.webp?v=1784877540","url":"https:\/\/store.motormia.co\/products\/304-stainless-steel-equal-length-exhaust-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
