{"product_id":"downpipe-exhaust-for-bmw-n54","title":"Downpipe Exhaust for BMW N54","description":"The Spelab 3-inch Turbo Downpipe is engineered specifically for BMW N54 engines found in the 135i, 1M, 335i, and 335is models. This performance upgrade replaces the restrictive factory downpipe, allowing the turbocharger to expel exhaust gases more efficiently. By reducing backpressure, this downpipe sharpens turbo response, increases horsepower and torque, and supports more aggressive performance tuning.\n\nConstructed from 3-inch diameter, 304-grade stainless steel, this downpipe features mandrel bent tubing and smooth radius bends to minimize turbulence and maximize exhaust flow. It incorporates a CAD\/CAM designed cast bell mouth for a seamless transition from the turbocharger flange to the pipe. The unit is TIG welded for superior strength and durability.\n\nThe product comes with a VRSF Lifetime Warranty against defects and fitment issues.\n\nFitment includes:\n- 2007-2010 E90\/E91\/E92\/E93 BMW 335i N54\n- 2011-2013 E92 BMW 335is N54\n- 2008-2010 E82\/E88 BMW 135i N54\n- 2011-2012 E82\/E88 BMW 1M N54\n\nThis product may affect catalytic converter or emissions equipment function and may not be legal for street use in all areas. Buyers are advised to check federal, state, provincial, and local laws before purchase or installation.","brand":"Spelab","offers":[{"title":"Default Title","offer_id":52871965835576,"sku":"SPES08316","price":148.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/downpipe-exhaust-for-bmw-n54","provider":"MOTORMIA","version":"1.0","type":"link"}
