{"product_id":"high-efficiency-downpipe","title":"High Efficiency Downpipe","description":"The Two Step Performance High Efficiency Downpipe is constructed from 304 stainless steel and features a 4.5-inch outer diameter with a 400 CPSI GESi G-Sport catalytic converter. Designed for Honda and Acura 1.5T engines, it provides increased airflow and power without requiring a tune and won't trigger a check engine light. This downpipe is compatible with both factory and most aftermarket exhaust systems, offering improved response and power delivery. It utilizes an investment cast inlet with CNC pocketing to blend turbine and wastegate flow smoothly into a tapered outlet, promoting efficiency and reducing exhaust gas temperatures. The welds are back-purged for enhanced heat tolerance and durability. It includes gaskets, stainless hardware, and an O2 sensor harness extension, and comes with a 24-month warranty on welding.","brand":"Two Step Performance","offers":[{"title":"Default Title","offer_id":52664040292664,"sku":"TSP-DWN-01-02","price":899.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687723831.jpg?v=1784332336","url":"https:\/\/store.motormia.co\/products\/high-efficiency-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
