I have them and I love them...
I bought them through the dealer and they instaled them for free...
When I first heard them fire it up I thought it was LOUD.
Compared to the stock pipes they were, but after a while they're really not.
I can putt out of the neighborhood without racket if I want, but they really bark when you want them to.
I have them on my 2005 Fatboy...great sounding pipe in my opinion. I am very happy with them. I don't think I would want pipes any louder than these however.
Have a set on my 06 Wide Glide. They look great but are a bit loud even for me. I wear foam earplugs when riding but overall really like the look & sound of the big shot pipes.
I just picked up a 1997 FXSTC a couple of weeks ago that have the V & H Big Shots. DEFINITELY loud, but sounds great to me. I must say that I'm a little self conscious warming it up at home...many houses close by. But, I'm not lookin' back!
