Our Customer in Australia comments, based on our 100 Cell Cats: 

"The sound is fantastic. I have the bypass pipes, Sport mufflers and the headers made the big difference. My neighbor has an R8 Audi, he couldn’t believe how good it sounds as well (awesome in his words). In combination with the tune & intake this made the biggest difference of the lot, really woke the car up."
