{"product_id":"stainless-steel-race-headers-1","title":"Stainless Steel Race Headers","description":"The Dansk Race Headers are a quality tuning product designed to enhance the performance of Porsche 911 models from 1965 to 1989. Constructed from stainless steel, these headers feature equal length, mandrel bent primary tubes and a motorsport merge collector, optimizing exhaust gas flow and scavenging while reducing back pressure. This contributes to a dyno-proven gain of +15 HP and +14 Tq.\n\nThese headers replace the stock heat exchangers and do not provide heat. They are sold as a set (left and right) and include connecting pipes for a dual inlet muffler. The primary pipe diameter at the inlet is 44 mm (1.7”) I.D., tapering to 42 mm (1.65”) I.D., with connecting pipes at 47 mm (1.8”) I.D. The product also has provisions for O2 or temperature sensors.\n\nPlease note that models after 1975 typically require a dual inlet muffler and an early style oil line conversion kit (part # FVD211328ANB). Importantly, these headers will not fit US model 911 3.0 L SC or 911 3.2 L vehicles. The product is intended for competition and off-road use only, and its use on public roads may violate federal, state, and local laws.","brand":"Dansk","offers":[{"title":"Default Title","offer_id":52687585706296,"sku":"170910242","price":4130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663678309.jpg?v=1784885316","url":"https:\/\/store.motormia.co\/products\/stainless-steel-race-headers-1","provider":"MOTORMIA","version":"1.0","type":"link"}
