Clear BMW chassis

Please ensure your correct model is selected

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

This N20 downpipe feature larger piping and catalytic converter that are freer-flowing than the original cats for better flow and less backpressure. By removing exhaust restrictions the turbos can spool up faster which makes more boost sooner. With additional tuning, more power is available. There are downpipes that delete the primary cats and can leave the exhaust with a dirty and awful smell. These Wagner downpipes are built with a sport cat to keep the exhaust cleaner.Special software, or stand-alone engine management, may be required to keep emissions fault codes and check engine lights from appearing.

Features:

  • 200cpi Catalytic Converter
  • 100% perfect fit - CAD designed.
  • less thermal load on the turbocharger
  • more power by reducing back pressure
  • significantly more torque
  • Made from 1.4301 (SS304) Stainless Steel
