i know this has been harped on again and again. I have a 2015 fat bob, I'm seeking to put in a 2-1 I like the rinehart but also the thunderheaders. Besides those two and including them which would yield best hp/to increases? I have hear the you tube comparison video and rinehart sounds louder deeper etc but also thunderheaders was really good did not like the two brothers the v&h pro pipe was not too bad and the broad rage II, also their several road rage II's out it last confusing and all. Any real numbers etc as well as pics yeh post feel free to give your 2 cents and I'll go from their.


thanks

 

I went through this also some time back. In my opinion, the two best performance 2-1 pipes are made by RB Racing and Frank Drago. Fit and finish is excellent. Keep in mind that performance pipes really stand out when engine mods are also added to the mix.
You really can't go wrong with any of the major manufacturers like, Vance and Hines, Rinehart, Fuel Moto, Rush, etc.
Btw, for just old school sound and power, hard to beat a Thunderheader...

 

The best performing 2-1, consistently time after time on the widest variety of engine builds, is the D&D.

 

I'll second this - I had a set of Bassani and D&D Fat Cats on my old Fat Bob, when I traded in for my SGS I went straight to the D&D

 

D&D hands down, every day!

 

I've tried V&H Pro Pipe, but my exhaust for life will be Bassani Road Rage.
It has surpassed all my expectations and it's sound is what I wanted in a everyday city/highway environment.
Quiet enough for late night rides through the neighborhood, can idle next to a cage without turning heads, but opens up in a formula one style sound when the throttle is opened up.

Here's some test data from Fuel Moto on various pipes, 2-1 included...http://www.fuelmotousa.com/p-33193-dyno-charts.html

 

wish could do the Rush wraths on my dyna with 2.50 0r 3.00 baffle.

 

If you like Rush, you might check out Frank Drago's website here:http://dragosbikeworks.com/

He designs his pipes, but are made by Rush. The Dragula 2 is one of the best bangs for the buck out there. And his customer service is as good as his product.

 

like rinehart 2-1 and thunderheaders and Rush they all have rear come out and go forward and back vs come straight down out of read exhaust port. I like that design but I like the sounds of those 3 too, but want serious hp/tq gains more so
