Soul Performance Valved Muffler (718 GT4 Cayman) 

We showcase the Soul Performance Valved Muffler for the 718 Cayman GT4 (or Boxster Spyder) and 4.0L GTS variants. This center section can really wake up the sound without going too aggressive. This client chose to keep the valves opened permanently as he uses it as a weekend/track car. This is with the stock headers and stock over axle pipes.
