{"product_id":"m113k-long-tube-headers-1","title":"M113k Long Tube Headers","description":"The Victory Road Performance E55\/CLS55 AMG Long Tube Headers are precision-engineered for the M113k platform, specifically for the 2003-2006 Mercedes E55 AMG and CLS55 AMG 5.4L models.\n\nThey include four O2 bungs and a CNC-machined 3\/8 inch thick flange, with dual TIG welds ensuring maximum durability. A flex section is also incorporated for enhanced fit and performance.\n\nInstallation is designed as a direct bolt-on setup with no modification required. However, weld-in catalytic converters are required with this product, and buyers can opt to add 200-cell or 400-cell cats, or proceed without them if they have their own to weld in. The product is intended for competition use only, and all other uses are contrary to federal law. Ceramic coated black headers are available as a free upgrade for a limited time.\n\nThese headers are dyno-proven to increase low-end torque and horsepower, improve throttle response, and provide an enhanced sound. They are compatible with RWD models only. Owners may also consider VRP ECU tunes for further performance enhancement.","brand":"Victory Road Performance","offers":[{"title":"Default Title","offer_id":52866471330104,"sku":"55KLTH","price":900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687396898.jpg?v=1787908827","url":"https:\/\/store.motormia.co\/products\/m113k-long-tube-headers-1","provider":"MOTORMIA","version":"1.0","type":"link"}
