LOL.... Never heard of a knock in a pipe before.

 

I'm running the S&S Sidewinder 2-1. Seems to runs to run better than my previous 2-1-2 setup.

 

Really like the look of the pipe itself and it I believe it would help with my dislike of only one pipe under one bag......next thought was how loud.........

My first impression on what it would sound like fits the above description......foiled again!

 

It's got a loud idle, rips when you get on it, but is surprisingly quiet out on the highway. Just did a 1,000 mile trip with GF on back no complaints

2 different exhaust systems. The LSR is baffled and the ProStock is not. I have the LSR and I feel it has a very classic tone as it is constructed with a heavy gauge steel, at idle it is nice, at cruise it is not loud, when you jump on it things start to get a bit loud, LOL

 

I have the D&D Fat Cat , and have been happy with it. Not ear splitting loud, but throaty enough to get you noticed. And I picked up hp and torque after the install. The fit and finish is second to none.

 

I have a Bassani Road Rage II in Flat Black on my 14 SGS. Love the pipe. Looks killer, sounds Killer. Find the one you like, as said 2:1 are all pretty decent.

 

If I was looking for a 2-1, Dragos would be my first call.

Exhaust is like oil the debate is endless.
Each engine will prefer a certain exhaust, for some reason.
I like a lot of the 2 into 1 exhaust.
Like the Bassani and V&H pro pipe hs, there are more that I like.
I suggest talking to folks at biker hang outs and have a listen for your self.

 

QTRRacer got it right on the LSR I have both the RBR LSR and RBR ProStock. The ProStock on the other hand is my favorite but will set off car alarms when I blip the throttle. It reminds me of my 1988 Super Glide with worked EVO and drag pipes!
