{"product_id":"4-race-downpipe","title":"4\" Race Downpipe","description":"The CTS Turbo 4\" Race Downpipe is a premium exhaust upgrade engineered for BMW F-series vehicles equipped with the N20 4-cylinder engine. The result is a noticeable increase in engine power, a more aggressive exhaust note, and a more responsive driving feel due to faster turbo spool and reduced backpressure.\n\nIt is rated to deliver a power increase of 25-35 HP, though this is octane-dependent and requires a Stage 2 tune for optimal performance and to prevent Check Engine Lights (CEL).\n\nThis part is specifically intended for off-road race use only and is not compatible with N26 engines. Installation requires a compatible Stage 2 tune (such as Bootmod3) to ensure proper engine operation and to clear CELs.\n\n*   2012-2017 F30 BMW 320i \u0026amp; 320xi (N20)\n*   2012-2017 F30 BMW 328i \u0026amp; 328xi (N20)\n*   2013-2017 F32\/F33 BMW 420i \u0026amp; 420xi (N20)\n*   2013-2017 F32\/F33 BMW 428i \u0026amp; 428xi (N20)\n*   2013-2017 F36 BMW 428i \u0026amp; 428xi Gran Coupe (N20)\n*   2012-2017 F20\/F21 BMW 128i \u0026amp; 128xi (N20)\n*   2013-2017 F22 BMW 220i \u0026amp; 220xi (N20)\n*   2013-2017 F22 BMW 228i \u0026amp; 228xi (N20)","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52872140357944,"sku":"CTS-DP-0020","price":275.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-race-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
