{"product_id":"3-inch-304-stainless-steel-downpipe","title":"3-Inch 304 Stainless Steel Downpipe","description":"The K-Tuned 9th Gen Civic Si Downpipe is engineered to enhance exhaust flow for the 2012-2015 Honda Civic Si models, including both 2-door and 4-door variants. It replaces the restrictive factory catalytic converter with a free-flowing 3-inch, T304 stainless steel pipe.\n\nThe downpipe starts with a cast stainless steel housing that provides a smooth transition from the exhaust manifold to the 2-bolt exhaust flange. The 3-inch diameter T304 stainless steel piping is TIG welded and routed carefully to clear the factory subframe and sway bar.\n\nFor enhanced sensor compatibility, the cast housing is equipped with two O2 sensor bungs. One is intended for the primary O2 sensor, and a second is included for an accessory sensor, complete with a plug for unused ports. K-Tuned includes all necessary hardware for installation, such as an O2 plug, serrated M8 nuts, an M8 bolt, and an M8 washer for the housing-to-head connection, though some original hardware may be reused. It is highly recommended to upgrade the rear engine mount to a Hasport rear mount to limit movement.\n\nThis downpipe is designed to mate perfectly with the K-Tuned 9th Gen 3-inch exhaust system, potentially leading to further performance gains when used as a complete system.","brand":"Ktuned","offers":[{"title":"Default Title","offer_id":52686532673848,"sku":"KRH-9TH-K24","price":424.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/659702001.jpg?v=1784874656","url":"https:\/\/store.motormia.co\/products\/3-inch-304-stainless-steel-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
