I have a FlowMaster on my truck and have about 15,000 miles on it. It's just a SI/DO. I think around 1000-1500 miles was when it got it's loudest and has been that way since.

I'm kind of disapointed in my Flow Master. I listened to videos of other Windsors with the Flow Master 40 and they sounded good and loud. Mine isn't loud at all, I can hear my engine over the exhaust most of the time.
