Fabspeed Primary Sport Cats with HJS High Flow Cats for BMW M5 (F9x) [S63]

Eliminate the heavy and restrictive factory catalytic converters with straight-pipe, high flowing stainless steel downpipes for maximum power and an exhilarating sound.


  • Fits all BMW F90 M5 vehicles (2017+).
  • Replaces the restrictive factory catalytic converters with high flowing 200 cell HJS catalytic converters for increased throttle response, and a more aggressive exhaust sound.
  • Constructed out of T304L stainless steel with CNC machined flanges and laser cut brackets.
  • Manufactured entirely in-house by our precision machine shop at Fabspeed Motorsport.
  • Designed to fit seamlessly with the factory exhaust system and are also compatible with any other aftermarket exhaust system that is designed to fit like OEM.
  • Direct replacement bolt-on complete German catalytic converter assemblies for the stock OEM restrictive catalytic converters.
  • Guaranteed no Check Engine Light – ultra high quality Extra large 130mm catalytic converters that will support over 1200HP. Obviously great for 600 to 900HP.
  • More power that any cat bypass pipe system while complying with emissions and not having a car stink and pollute the environment.
  • CNC precision billet stainless steel inlet and outlet flanges. Fit into “HOT V” on the engine.
