I had them in my V&H Side Shots for about 2000 miles:

QQ Thunder Monster Baffles for pipes with an inside diameter of 2" and outside diameter of 2 1/8".
Some of the pipes these fit: Vance & Hines Big Shot Staggered, Big Shot Long, Side Shots, Vance and Hines HS pipes, Screaming Eagle 16 Gauge for Softail/Dyna, Python Staggered Duals. These are only examples of pipes and you will need to measure your pipes for proper sizing. BCT part # QBL 1994, they retail for $129 plus shipping.
I sold the side shots and the buyer did not want the BCT baffles .... will sell for $75 plus shipping.

 

bump .... new price $60 plus shipping

 

BUMP for a good deal.
Just put a set of QQ's on my bike this week, they sound great, I paid $150 shipped to my house so this is a great deal for someone, don't miss out.
