Which is better stock pipes or true duals?
The stock head pipes give you more low end and mid range compared to the true duals with which you will gain some on the top end but lose down low. The D&D fat cat 2 into 1 seems to be an excellent alternative to the factory system.
What’s the difference between drag pipes and 2 into 1 exhausts?
Drag pipes just wouldn’t be drag pipes if there was a collector stuck on the end of them. With all of this in mind, there are a couple of fundamental differences between 2:2 and 2:1 exhausts when it comes to design. The advantage of a 2:2 is that the pipes are separate so the length can be fine tuned for a specific power band.
Is it possible to make a 2 into 1 exhaust system?
Does it make any sense to try to create a 2:1 exhaust system by blocking one side of the stock header after the crossover tube. Using slip ons, of course. You will not benefit from that modification. The end result will not have the same flow or back pressure as an engineered 2 into 1 assembly. I have short shots on a 2017 Street Bob.
Which is better a 2-1 or 2-2 head pipe?
I’ve seen some head pipes (front and rear) partially obstructed by the cross-over, not a good thing. As mentioned, a 2-1 makes the most gain followed closely by a 2-2. You’ll notice very little difference between a 2-1/2-2 on a basically stock motor. The difference will be more pronounced on medium to highly modified motors.

Which is the best pipe for a V-twin?
The best deal would be to have it tuned on a dyno. The xover pipe improves exhaust scavenging. the best performance on the harley v-twin comes from a 2-1 pipe while a 2-2 may look and sound cool you will lose some performance most noted in low end torque.
Is there a crossover in between the pipes?
They have a crossover welded in between the pipes like the V&H power chamber has – they said they got more performance WITH the crossover. This combined with the Andrews 26 cams, V&H VO2 air cleaner system, and Kury Crusher mufflers tuned with the TTS has made this bike an amazing pulling machine.
