The 997 GT3 is proclaimed as one of the best cars Porsche produced. Without a doubt, the GT3 is an absolute animal on the street or track. Be that as it may, we feel the GT3 doesn't quite have the tone it needs to let the Mezger really sing! The SOUL Center Muffler Bypass not only increases the invigorating flat six tone, it adds a dash of panache. The SOUL system is the perfect blend of street and track with the ability to be daily driven. Add a set of headers to give your GT3 that true track tone!
