{"product_id":"performance-downpipe-4","title":"Performance Downpipe","description":"This design facilitates increased gas flow, leading to improved engine efficiency and significant power gains when used without a catalyst. Constructed from aerospace-grade Type 304, non-magnetic stainless steel, this downpipe offers superior durability and resistance to discolouration.\n\nMandrel bending ensures consistent radius bends for optimized gas flow, while the enlarged bore diameters are carefully calibrated to maximize performance without sacrificing mid-range torque. The exhaust systems undergo a comprehensive acoustic development process to deliver a sporty and crisp tone, free from NVH, drone, or cabin resonance.\n\nThis product is intended for track use or motorsport applications only and requires a Stage 2 ECU remap. Using this de-cat downpipe will prevent your vehicle from passing an MOT test, as only EC type-approved components are legal for road use.","brand":"Milltek","offers":[{"title":"Default Title","offer_id":52689131569464,"sku":"MIL-SSXAU817","price":836.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687385147.webp?v=1784902308","url":"https:\/\/store.motormia.co\/products\/performance-downpipe-4","provider":"MOTORMIA","version":"1.0","type":"link"}
