The Granatelli Motor Sports 2.25 in electronic exhaust cutout opens a bypass ahead of the muffler at the press of a switch, letting exhaust exit before the rest of the system. This is the aluminized mild steel slip-fit version, supplied as a dual kit.

Key Features

  • CNC-machined 6061 aircraft-quality aluminum cutout body

  • Stainless steel butterfly plate and blade shaft
  • Drive gears machined from high-temperature carbon steel
  • Built-in circuit prevents over-torquing the butterfly if the switch is held down
  • V-band clamp lets the turndown rotate a full 360 degrees for placement
  • Polished stainless steel 45 degree turndown aims the discharge at the ground rather than out the side, which helps keep fumes out of the cabin
