I like the 2 into 1 drag pipes or the dual shorty chopper style. anyone have these? I have a 2012 blackline

 

I have used santee drag pipes many of times. However, with your motor I would not recommend using a drag or short pipe. Motors like your like back pressure for power. If you want just loud as **** go for it. But you will sacrifice a ton of power. If you want performance then you have to use a baffled pipe

 

I don't have Santee's but have V&H with BCT baffles and they make good power, not as much as a good 2-1 pipe. But you don't loose that much..IMO, I have what I want to look at, not what makes the most on a dyno, They are louder than a 2-1 but just don't like the looks of the long 2-1 pipes or the sound of them
