{"product_id":"304-stainless-steel-downpipe-with-gesi-cat","title":"304 Stainless Steel Downpipe with GESI Cat","description":"The Cobb Stainless Steel Downpipe is engineered as a direct replacement for the Ford Focus ST Ecoboost 2.0L models from 2013-2018. Constructed from durable 304 stainless steel, this downpipe features a high-flow 300-cell GESI catalytic converter designed to improve exhaust flow.\n\nInstallation is facilitated by a CNC-machined V-band flange and a 4-inch flex section, ensuring an OEM-like fitment at the turbocharger. The design incorporates adjustability at the lower downpipe mount through slotted attachment points, allowing for a custom fit and reducing strain on rubber isolators for enhanced long-term reliability. Furthermore, a cast stainless 3-inch flange replaces traditional laser-cut plates, offering greater rigidity to prevent warping and potential exhaust leaks during installation and operation under extreme heat. A multi-layer steel gasket ensures a leak-free seal with the cat-back exhaust system.\n\nThis downpipe provides a free-flowing exhaust outlet, aiming to reduce turbo back pressure and increase turbo efficiency, positioning it as a key component for achieving Stage 3 power levels. COBB Tuning offers off-the-shelf Stage 3 maps for the Focus ST Accessport to complement this upgrade.\n\nIMPORTANT: This product is supplied with all necessary gaskets and mounting hardware and DOES NOT require welding.\n\nNOTICE: This product is for RACE USE ONLY and is not intended for street use or public roads.","brand":"Cobb","offers":[{"title":"Default Title","offer_id":52687424291128,"sku":"591220","price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660685789.webp?v=1784883920","url":"https:\/\/store.motormia.co\/products\/304-stainless-steel-downpipe-with-gesi-cat","provider":"MOTORMIA","version":"1.0","type":"link"}
