First let me give you a little info.
The bike is a 2009 FLHTPI with D&D Fatcat 2 into 1 exhaust, a big sucker air cleaner, and a Power Commander V. I got on the bike 2 nights ago and noticed that the exhaust note had changed drastically. Like the bike is half as loud as it used to be. (and no it isn't my hearing, I can hear music louser than it used to be.)
I'm hoping that someone may have had this experience before and can lead me in the right direction as where to look at what may be causing this.
The fact that it isn't as loud doesn't bother me as much as the fact that I didn't change anything that would cause this.
Thank you in advance for the assistance.
So what your saying is it was louder when you bought it and it's tamer overnight? Exhaust will seem louder with a helmet on as apposed to not wearing a helmet. It shouldn't get tamer unless you added packing to the baffles, so what the hell.
This has me stumped. haven't changed anything...
No helmet, didn't add anything to the exhaust, haven't switched windshields.
From Idle to just under 3K RPM's the sound now reminds me of when I had stock pipes on the bike.
