So i just installed a thermal catback system on my gsx. Has a nice tone but not like if heard on other peoples. Most ones i hear have a deep growl almost like a subaru. Mine just has a deep hum or tone. Im a little confused as to why i dont hear the same sound from mine. It also has a 3inch downpipe.
