{"product_id":"4-2-1-long-tube-race-header","title":"4-2-1 Long Tube Race Header","description":"The Weapon R 953-118-101 is a 4-2-1 stainless steel race header engineered for the 2003-2006 Mazda 6 with a 4-cylinder engine. Its long tube, stepped tubing design is optimized for maximum high RPM exhaust flow and higher torque gains across the power band, making it ideal for competition racing and high-revving applications. The header features a 2.5\" collector to further enhance exhaust flow.\n\nThis race header is designed with extensive research and development on Weapon-R's Dynapack Dyno, achieving a reported gain of 14.7 HP and 11.1 TQ with the header alone. It is intended for off-road use only and is not street legal as it eliminates the catalytic converter. A CEL (Check Engine Light) eliminator is available and recommended for these applications.\n\nProfessional installation is recommended for this header. It is explicitly designed for the 2003-2006 Mazda 6 4-cylinder models and is not compatible with other vehicles or engine configurations.","brand":"Weapon R","offers":[{"title":"Default Title","offer_id":52689749934392,"sku":"953-118-101","price":446.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687766717.jpg?v=1784909939","url":"https:\/\/store.motormia.co\/products\/4-2-1-long-tube-race-header","provider":"MOTORMIA","version":"1.0","type":"link"}
