{"product_id":"k-series-header-downpipe-w-cat","title":"K-Series Header Downpipe w\/ Cat","description":"The PLM Power Driven K-Series Header Downpipe is engineered for maximum performance for the 9th Gen Honda Civic FG (2012-2015) and Acura ILX (2013-2015). It features a substantial 4.25-inch bell mouth and a 3-inch outlet, designed to significantly improve exhaust gas scavenging and flow. The one-piece design is constructed from durable 18-gauge stainless steel, ensuring longevity and resistance to corrosion.\n\nThis header downpipe integrates a high-flow, 200-cell metallic core catalytic converter, balancing performance gains with emissions compliance. The package includes necessary gaskets, hardware, and an O2 sensor adapter, along with an additional bung for a wideband sensor.\n\nKey construction details include CNC machined manifold flanges with a 0.38-inch thickness, a high-grade casting on the bell mouth section, and precision CNC mandrel-bent tubing. It also incorporates a braided flex pipe section with an interlock liner for added durability and flexibility. A one-year limited warranty is included.\n\nCompatible vehicles are the 2012-2015 Honda Civic Si (9th Generation Civic FG4) and the 2013-2015 Acura ILX. One forum discussion noted a potential fitment issue with the steering rack on a 2012 coupe, and the recommendation of a rear motor mount for optimal installation.","brand":"PLM","offers":[{"title":"Default Title","offer_id":52663281451320,"sku":"PLM-HFG4-HEADER","price":475.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687525468.jpg?v=1784325584","url":"https:\/\/store.motormia.co\/products\/k-series-header-downpipe-w-cat","provider":"MOTORMIA","version":"1.0","type":"link"}
