Do I need an existing Fabspeed part for this to work?
Yes, this kit requires an existing Fabspeed 993 Sport Cat X-Pipe or Catbypass X-Pipe already installed.
How quickly can I switch between street and track setup?
Fabspeed says you can disconnect two clamps per side and swap in minutes, then repeat the process to switch back.
