Power duels vs Pro pipe?

I am planning on doing an exhaust change with AC and cam over the winter. How much of a performance difference would I see between the two systems. I have a stock 2013 Ultra Limited 103. I like the looks of both. I am thinking Se 204 0r 255 for the cam.

I have a stock motor with the propipe and my friend has the same bike, same intake, same tuner, but a 2-2 pipe. With my propipe I still beat him in horsepower (stock cam) and torque. And the same guy dyno tuned it. I think it was about 2hp (96 motor)

A lot on these two pipes will depend on the tune. We have a member (strokerjik) who gets great results with the power duals, but he knows what he's doing tuning.

In theory though, a 2-1 should bring power on sooner and carry it out further than a dual setup, but there are always so many variables, such as choice of cams, person tuning, other work done or not done to the motor, etc.

I would suggest finding who's going to do your work first and then going from there.

To me it's a no brainer. A good 2in1 pipe will always out perform any dual pipe period. Some guys can't handle the look of the single pipe so they sacrifice the performance. For a simple stage one it's no big deal. But if you are spending big dollars on an engine build then you want the best performance. As far as how much difference, you'd have to look at some dyno charts. Then again, it depends on the tune. You could be looking at a 10-15 hp difference just on you choice of pipe.

To answer the OPs question, minimal.

For all the 2 into 1 affecianados, why is it that every year at Bonneville there are 4 times as many v-twin dual exhaust setups as there are 2 into 1s? and don't give me the low end torque reply cause, with the exception of the "holeshot" noone max performs with low end torque.

Just wondering while munching popcorn

The V&H Power Duals are not a 2-2 system. They are a 2-1-2 system. I had both the Power Duals and a 2-1 on my 120" Eglide and I can't honestly say the butt dyno feels much difference.

The power duals or Jack Pot 2-1-2 will give up very little over a 2 into 1 but will be quieter and have a flatter torque curve. A properly tuned 2 into 1 may give you more peak #s but sometimes on a mildly tuned motor it's not what you may think is worth it. The #s some folks advertise are not false but are usually compaired to a very poor exhaust system.
