The factory M3 and M4 mid-pipe uses two resonators that muffle the S58 and restrict flow. CTS Turbo replaces them with one straight 3.5 in stainless pipe without a resonator. You get a louder, deeper note and better flow, without unnecessary drone.

What you get

  • Single 89 mm (3.5 in) pipe replacing the factory dual mid-pipe.
  • SS304L stainless steel with CNC mandrel bends that keep welds to a minimum.
  • Stainless tunnel brace included, modeled on the factory part.
  • Works with factory or aftermarket downpipes.

Good to know

  • Install needs two cuts in the factory pipe, at the dimples BMW marks for service. It can be reversed later.
