I have tried my Carpy pipes with and without baffle. 120dB with baffle out and 90dB with it in. I have never had a Harley rider look at me like my bike was annoyingly loud before, until now. People hate that pipe without the baffle. My neighbors flip me off, and the women and children hold their ears. Kinda cool!
BTW Dig around in that box real good to look for the baffle. It is a little tiny thing, and he just threw mine in the box. I had to fish out all the packing peanuts to find it.
I'm on my second baffle, too! The first got ejected somewhere on the highway. I like to think it shot out like a grenade, but it probably just wiggled out. I have modified the new baffle to allow the bolt to go all the way through it. Those 2 or 3 threads just don't hold it in very well, even with Loctite.
