CP-E Catted Downpipes BMW N54

  • cp-e downpipes for twin-turbo N54 BMW cars are the product of nearly ten months of design work, and represent the latest in reverse-engineering and manufacturing technology. The downpipes are constructed from heavy gauge American-made 304-stainless steel, and also carry a lifetime warranty.

    The visually striking stainless bellmouth castings are both attractive and functional. Each was designed entirely in CAD space, and is contoured internally to provide the lowest resistance to exhaust flow possible. This allows the turbos to effectively evacuate exhaust from the turbine housing, which decreases engine pumping losses as well as improve turbo responsiveness. The thick-wall castings help retain exhaust energy as well as prevent cracking from the thousands of thermal cycles daily driven vehicles endure.

    The ultra-precise fitment of the downpipes in what is an incredibly small workspace is the result of painstaking attention to detail and the utilization of state-of-the-art manufacturing equipment. cp-e utilizes the latest in 3-D digitizing and reverse-engineering tools, and also take advantage of robotic cutting and welding systems to reduce the influence of human error. These tools ensure that each example is true to the original prototypes, which guarantees ideal fitment each and every time.

    The downpipes may be installed without any permanent modifications, and are available with or without high-flow catalytic converters and additional wideband oxygen sensor bungs.

    Includes spun-metallic catalytic converters.

    Fits all N54-powered E90 and E82-series 335i and 135i.
