Wagner Cat-less Downpipe - N55 - F22 M235i, F30 335i, F32 435i - 7/2013+

Eliminate the biggest restriction in the F22 and F30/1/2/3/4 N55 exhaust system by deleting the primary catalytic converter. On a track car, cats are no longer needed or wanted. They rob the turbo engine of power and torque, contribute excessive heat build-up, and lead to a total blockage if the catalytic material fails. This Wagner cat-less downpipe solves all of that by having no restrictions through its oversized diameter piping. Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.


  • made out of high quality stainless steel 1.4301 (SS304)
  • 100% perfect fit, replace OEM
  • less thermal load on the turbocharger
  • more power by reducing back pressure
  • significantly more torque
  • connection diameter 105mm
