MAD BMW N55 F10 535 / F12 640 EWG Catless Downpipe
The MAD Catless Downpipe is designed for 2014+ BMW F10 535 and F12 640 models equipped with the N55 engine and electronic wastegate turbocharger. Its unrestricted catless design improves exhaust flow while giving the turbocharged inline-six a more aggressive exhaust note.
Improved Flow for the N55 EWG Platform
Replacing the factory catalytic downpipe reduces restriction immediately after the turbocharger. The freer-flowing path is well suited to BMW enthusiasts seeking sharper response, a stronger exhaust character, and additional support for performance-focused N55 builds.
An integrated flex section accommodates movement within the exhaust system, while the formed tubing, mounting provisions, and sensor ports provide an application-specific layout for the F10 and F12 chassis.
