Fabspeed Porsche 911 Carrera Supercup Exhaust System (1976-1989)


Fabspeed Porsche 911 Carrera Supercup Exhaust System (1976-1989)


This racing inspired exhaust system replaces the restrictive factory muffler with a free-flowing resonated design to immediately bring out the roaring sound of the 3.0L / 3.2L engine.


The Fabspeed Supercup Exhaust is the loud and proud system that's aggressive enough that we recommend it for track use only.


  • Fits all Porsche 911 Carrera Vehicles 1976-1989
  • Very aggressive muffler bypass type system which incorporates two resonators to slightly tone the sound down compared to our straight Muffler Bypass
  • Saves 8 lbs from the rear of the vehicle
  • Single outlet design with a Deluxe 4.5" Oval Style Tip
  • Direct replacement for the OEM muffler and will bolt to the factory catalytic converter or a similar product in its place
  • Complete T304L stainless steel construction; 14-16ga CNC mandrel-bent 2.25” tubing
  • Simple DIY bolt-on installation, no cutting or welding required
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
