I've got Short Shots on my Street Bob and love the sound and looks. They give the bike more of a hot rod look I think.

 

Yeh, they are the staggered ones.
Not really sure of the differences.

 

I have the black ones on my 08 soft tail custom with the quiet baffles in.
I love them.
The tech at the dealership said he loved the sound of my bike and I know he's heard alot of them.
Its quiet for the nighbors but when I give it throtle its loud.
And I am suprised at the bikes I'v been able to pullaway from that are suposed to be faster than me.
