I would love to hear what people sat here. Stephano from MotoWheels recommended the Zard Penta Evo for my '14. He said it had a great sound and is not as loud as my SC-Project CR-T with decat. Not sure how it compares with Termi, MIVV, Arrow, etc.
He said: "I do understand exactly as to what you are trying to achieve and based on what I’m hearing from you here, this is the one I would highly recommend. You can’t go wrong with this system as it will provide a nice deep tone without being too loud and obnoxious. It’s a lovely system with great quality built into it:"
