{"product_id":"3-inch-catless-downpipes-4","title":"3-Inch Catless Downpipes","description":"The ARM N63DP catless downpipes are engineered to significantly increase power and torque for BMW models equipped with N63\/N63TU 4.4L V8 Twin-Turbo engines. Constructed from durable 304 stainless steel with a 3-inch diameter, these downpipes optimize exhaust flow from the turbochargers to the mid-pipe.\n\nThey incorporate a flex section and a reinforced bracket that attaches to the transmission housing, mitigating stress on the turbochargers and ensuring a secure connection. The inclusion of two O2 sensor bungs on each downpipe allows for the retention of factory O2 sensors and heat shields, ensuring proper data transmission to the DME for smooth engine operation.\n\nThis product is intended for off-road use only and is not legal for use on public roads in most states and provinces. European owners should note that these downpipes will not fit vehicles with the OPF (Otto Particulate Filter) system, typically found on Euro 6c\/6d emissions vehicles. Visually inspecting for large filter canisters near the turbos is the best way to confirm compatibility.\n\nThe downpipes are compatible with a range of BMW models including the 550i (F10\/F07), 650i (F06\/F12\/F13), and 750i (F01\/F02), as well as Alpina variants. Fitment is specific to vehicles with a slip-fit style OEM downpipe connection to the mid-pipe.","brand":"Arms Motorsport","offers":[{"title":"Default Title","offer_id":52686963081528,"sku":"N63DP","price":397.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660183619.webp?v=1784879001","url":"https:\/\/store.motormia.co\/products\/3-inch-catless-downpipes-4","provider":"MOTORMIA","version":"1.0","type":"link"}
