My Ride: 2005 BMW 545i, Billy Boat w/ y-resonator removed.
Well, the weather cleared a little bit in time for Christmas here in Michigan so I was able to get a better feel for the mods on the highway and more performance driving.
The car rev's better, thats for sure. It was somewhat noticable after just the basic install of the Billy Boat, but with the y-resonator removed it's even more pronounced.
Sound - with the y-resonator removed - under 60mph you can hear it in the car. It only gets a little loud right at 50. Above 60 and it mellows out pretty well. Sitting in dead silence in the car at 80 mph you can hear it a little bit. If your holding a conversation, have the radio on, or the heater fan on a couple clicks you can't hear it. So that's good. I was concerned that taking the y-resonator off might give it a drone at highway speed.
Full throttle take offs - schweet! I'll try and get a "take off" video posted up
