BMW B48 Catted Downpipes

Eliminating restrictions in the exhaust system is key to increasing efficiency and power. Back pressure causes delayed turbocharger response and is a bottleneck.

cp-e™ cast stainless downpipes have been designed specifically for the B48 motors to reduce back pressure and optimize exhaust flow.

+12whp +10wtq
CAD designed castings channel the gas from the twin turbos into mandrel bent tubing – as a result there are no harsh bends or transitions restricting flow. Made completely of high grade 304 Stainless steel, the system is strong and durable.

The ultra-precise fitment of the downpipes 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.


While this may not trip a Check Engine Light, we cannot guarantee that all of the codes will be in the “ready” state. Check engine light will depend on your particular setup, tune, and other vehicle modifications.
