Ha, it's an interesting system (chambered cat back). Under 2,800 it's quiet enough that neighbors/police officers don't even glance at the car when I go by. When it hits 2,900, it's like a valve opened, sound level doubles. And sounds really good. At 70mph in 5th or 6th, it's not much louder that stock, hardly noticeable. And no drone. |
