I have the Bassani ORY and am very Happy with it but I also installed a Borlamouth and it just got better. The ORY did increase the volume of my stock exhaust. It sounded good at WOT but it was a bit raspy and untuned. After the Borla XR-1 muffler the sound became much deeper and refined. It probably gained somewhere between 5-10rwhp.
