{"product_id":"3-inch-catless-downpipes-3","title":"3-Inch Catless Downpipes","description":"The ARM Motorsports 3-inch catless downpipes are engineered to enhance the performance of N54-powered BMW 335i, 135i, and 1 M Coupe models. By removing the restrictive OEM catalytic converters, these downpipes facilitate a freer exhaust flow, leading to significant gains in both horsepower and torque. They are constructed from durable 304 stainless steel, designed to optimize exhaust flow and manage back-pressure effectively.\n\nEach downpipe features two O2 sensor bungs, allowing for the remounting of factory BMW O2 sensors. This ensures the ECU can continue to monitor exhaust gases. However, due to the catless design, an ECU tune or a CEL (Check Engine Light) fix will be necessary to prevent a CEL from appearing on the instrument panel. Installation may require an ECU tune to function correctly and avoid error codes.\n\nThese downpipes are specifically designed for Rear-Wheel Drive (RWD) vehicles only and are compatible with the following BMW models: E82 1 M Coupe, E82 135i, E88 135i, E90 335i, E92 335i, E92 335is, E93 335i, and E93 335is, all equipped with the N54 3.0L engine. Please note that this product is intended for Off-Road Use Only and may be illegal to use on public roads in many jurisdictions. ARM Motorsports backs this product with a lifetime warranty against defects in craftsmanship and fitment.","brand":"ARM","offers":[{"title":"Default Title","offer_id":52686962164024,"sku":"N54DPRWD","price":281.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660676302.webp?v=1784878991","url":"https:\/\/store.motormia.co\/products\/3-inch-catless-downpipes-3","provider":"MOTORMIA","version":"1.0","type":"link"}
