cp-e™ is very proud to offer replacement cast stainless steel downpipes
for the BMW N54 twin-turbo engine. The cp-e™ downpipes are the product
of nearly 10-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 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.
The 3" Downpipes will come complete with step by step
instructions and all necessary hardware required for a complete and
professional installation.
