{"product_id":"1-5-8-stainless-steel-shorty-headers","title":"1-5\/8\" Stainless Steel Shorty Headers","description":"These headers are precisely manufactured with mandrel bent tubing and tig welded for optimal flow and longevity, featuring a natural stainless steel finish that signifies their raw material quality. All Speed Engineering headers have been dyno proven to deliver measurable performance gains.\n\nKey features include 1-5\/8\" primary tube diameters and 2-1\/2\" collectors, designed to increase horsepower by over 12 rwhp. This specific model is a race version that omits Air and EGR fittings. The CNC machined flanges ensure a precise fitment, and the package includes standard graphite manifold gaskets. Installation is straightforward, though customer feedback suggests that longer M10 exhaust bolts may be necessary, and using OEM manifold gaskets is recommended for optimal sealing.\n\nThese shorty headers are specifically designed for V8 engines, including 5.3L and 6.2L applications. Vehicle fitment includes 2014-2018 Chevrolet Silverado (2wd\/4wd), 2015-2018 Chevrolet Tahoe (2wd\/4wd), 2014-2018 GMC Sierra (2wd\/4wd), 2015-2018 GMC Yukon \u0026amp; Denali (2wd\/4wd), and 2015-2018 Cadillac Truck \u0026amp; SUV (Awd). It is important to note that GM 2500\/3500 models with 6.0L applications will require different Speed Engineering exhaust products.\n\nAdditionally, there is a restriction: these headers will not ship to California. While no specific post-install tuning is explicitly mentioned, the performance gains and race version nature suggest optimal performance may be achieved with accompanying engine tuning.","brand":"Speed Engineering","offers":[{"title":"Default Title","offer_id":52663768056120,"sku":"25-1040","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687686666.jpg?v=1784329444","url":"https:\/\/store.motormia.co\/products\/1-5-8-stainless-steel-shorty-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
