{"product_id":"1-625-inch-primary-shorty-exhaust-header-1","title":"1.625-Inch Primary Shorty Exhaust Header","description":"The Doug's D3320-B is a shorty exhaust header engineered to provide a performance upgrade over restrictive stock manifolds. Designed as a direct bolt-on replacement where underhood clearance is limited, it improves exhaust flow and can free up horsepower. The header is constructed from durable 16-gauge steel tubing with 0.375-inch thick machined flanges to prevent warping. Its CNC mandrel-bent tubes ensure an accurate fit and optimal flow.\n\nKey specifications include 1.625-inch primary tubing diameter, a 3-inch round port collector diameter, and a 3-bolt flange collector attachment. The header is finished with a durable, matte Hi-Temp Black Coating, offering protection against rust and corrosion while providing a subtle, aggressive style.\n\nThis header includes a fitting to accept the stock O2 sensor and comes with both gaskets and mounting hardware for a straightforward installation. It is specifically designed for 1982-1992 Chevrolet Camaro and Pontiac Firebird models equipped with Small Block V8 engines (5.0L 305ci, 5.7L 350ci).\n\nPlease note that this header is legal for off-highway use only, excluding California or states using California emission standards. It is intended for vehicles produced before emissions control regulations or for closed-course competition use. Always consult the manufacturer's application guide and installation instructions for proper fitment and legal compliance.","brand":"Dougs","offers":[{"title":"Default Title","offer_id":52860284469560,"sku":"D3320-B","price":492.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687896571_8df2634f-541f-4769-945c-02172dfd1c12.jpg?v=1787766451","url":"https:\/\/store.motormia.co\/products\/1-625-inch-primary-shorty-exhaust-header-1","provider":"MOTORMIA","version":"1.0","type":"link"}
