cp-e QKspl Bellmouth Downpipes Catted 3in BMW 335i 2007-2010 / 135i 2008-2010 / 1M 2011 w/ N54
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 n54 motors to reduce back pressure and optimize exhaust flow.
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.
•Full 304 Stainless construction
•Cast bellmouths for smooth transitions
•Mandrel bent tubing
•Laser cut flanges
•Made in the USA
