{"product_id":"3-inch-catless-downpipes-2","title":"3-Inch Catless Downpipes","description":"The ARM Motorsports 3\" catless downpipes are engineered to elevate the performance of your N54-powered BMW 335i. By removing the restrictive OEM catalytic converters, these downpipes facilitate a significantly freer exhaust flow, directly translating to increased horsepower and torque. This improved flow is crucial for vehicles running higher boost levels, such as those utilizing Stage 2 tunes and beyond.\n\nConstructed from durable 304 stainless steel with a 3-inch diameter, the ARM downpipes are designed for optimal exhaust flow and back-pressure. Each downpipe includes two O2 sensor bungs, allowing for the remounting of factory BMW O2 sensors to maintain exhaust gas monitoring by the ECU. It is important to note that due to the catless design, an ECU tune or a CEL (Check Engine Light) fix will be necessary to prevent a dashboard warning light.\n\nThis product is specifically designed for RWD vehicles including the BMW E82 1 M Coupe, E82\/E88 135i, and E90\/E92\/E93 335i and 335is models, all equipped with the N54 3.0L engine. The downpipes come complete with a hardware kit and new gaskets for installation. ARM Motorsports offers a lifetime warranty against defects in craftsmanship or fitment. Please be aware that this product is intended for Off-Road Use Only and is illegal for use on public roads in most states and provinces.","brand":"ARM Motorsports","offers":[{"title":"Default Title","offer_id":52664199905592,"sku":"N54-DP-3","price":297.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/686899443.webp?v=1784335070","url":"https:\/\/store.motormia.co\/products\/3-inch-catless-downpipes-2","provider":"MOTORMIA","version":"1.0","type":"link"}
