{"product_id":"3-catless-downpipes","title":"3\" Catless Downpipes","description":"The ARM Motorsports 3\" Catless Downpipes are engineered to elevate the performance of your BMW N54-powered 335i. By eliminating the restrictive OEM catalytic converters, these downpipes allow for a freer exhaust flow, which directly contributes to significant gains in both horsepower and torque. The design is specifically tailored to accommodate higher boost levels associated with Stage 2 tunes and beyond.\n\nConstructed from durable 304 stainless steel, these downpipes are built to withstand the demands of performance driving. The 3\" diameter ensures optimal exhaust flow and back-pressure management. Each downpipe includes two O2 sensor bungs, allowing for the seamless remounting of your vehicle's factory O2 sensors. It is important to note that due to the catless design, an ECU tune or a Check Engine Light (CEL) fix will be required to prevent a CEL from appearing on your instrument panel.\n\nThe package includes the ARM 3\" Catless Downpipe Set, a hardware kit, and new gaskets for installation. ARM Motorsports offers a lifetime warranty on all their products, covering defects in craftsmanship and fitment. Please be aware that these downpipes are intended for Off-Road Use Only and may be illegal for use on public roads in many jurisdictions.","brand":"BMW","offers":[{"title":"Default Title","offer_id":52687209824568,"sku":"N54DPRWD","price":281.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660681151.webp?v=1784881416","url":"https:\/\/store.motormia.co\/products\/3-catless-downpipes","provider":"MOTORMIA","version":"1.0","type":"link"}
