Circuit Werks Latest BMW M57N2 Diesel Downpipe! Designed with ease of mind when it comes to a better flowing Direct Stock replacement for the Euro Models only! Our downpipe is designed to maximize performance by improving exhaust flow, lower exhaust gas temperatures as well as increase fuel economy and horsepower.

This downpipe is a direct stock replacement.  It’s made from high quality stainless steel that is mandrel bent and TIG welded. 

Also features bung fittings that are welded on for use of

  • O2/ Lambda Port 
  • Two ports for Temp Sensor
  • Sensor tube for the pressure measurement tube
  • Mounting bracket for a secure fit.
  • 3.5" Turbo Inlet
  • 3" Piping

We recommend for best performance, fuel economy, and emission results, adjusting the factory tuning ECU settings, as well as turning the DPF cleaning cycle off. 

This Downpipe will fit European models only (As the US models have different lower flange and will require modifications, if installed on a Non-European made model).
