{"product_id":"m113k-long-tube-headers-2","title":"M113k Long Tube Headers","description":"The VRP E55\/CLS55 AMG Long Tube Headers are precision-engineered for the M113k platform, offering a significant upgrade over factory log manifolds. These headers are designed to enhance exhaust flow, particularly at higher RPMs, with an estimated 35% improvement in exhaust gas flow. This upgrade is intended to provide enhanced power and efficiency.\n\nThe runner wall thickness is 16 gauge, and they include four O2 bungs and dual TIG welds for maximum durability. A flex section is incorporated to improve fitment and performance. Installation requires the use of weld-in catalytic converters.\n\nThese headers are listed as a direct bolt-on setup with no modification required. They are dyno-proven to increase low-end torque and horsepower, offering improved throttle response and an enhanced sound. The product is for competition use only, and users are cautioned against purchasing or installing for highway or non-competition off-road purposes.\n\nApplication is specific to the 2003-2006 Mercedes E55 AMG 5.4L and 2003-2006 Mercedes CLS55 AMG 5.4L models. Crucially, these headers **only fit RWD (Rear-Wheel Drive) models**.","brand":"VRP (Victory","offers":[{"title":"Default Title","offer_id":52866544599352,"sku":"55KLTH","price":900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687406513.jpg?v=1787909257","url":"https:\/\/store.motormia.co\/products\/m113k-long-tube-headers-2","provider":"MOTORMIA","version":"1.0","type":"link"}
