Does the fuel moto 2-1-2 x-headpipe work as good as a 2-1. The dyno charts look good as far as bottem end torque go, but is a 2-1 still a lot better? I love the look of my dual mufflers but if going to a single makes her pull better Im willing to sacrifice the looks for more bottem end.

 

depends on the specific design of the 2/1 ( how long each head pipe is) as to where the peak torque is produced...and that depends on cam choice.

so yes/no, maybe...


a 2/1 works well on smaller bikes ( fxr/dyna/sporty) as their exhaust systems are smaller.

The touring series 2/1/2 has so much available volume that the system makes better power just due to it's size.

if you were to compare bagger dyno charts to dyna charts, the difference in power ( a few HP) is due to the exhaust system, the motors are the same ( the softail series uses a different version of the twincam, the B motor)


some baggers with a 2/1 have a dummy on the left side--- I've even seen them with storage compartments

2-1 will turn more torque quicker down low in the 2500-3200 rpm range , above that there is not much difference , I was at a tuners shop that has tuned many fuel moto 2-1-2 pipes , and although they are a good pipe the 2-1's turned more torque quicker dowm low , over all numbers were similar

 

Thanks, this is exactly what I was wondering. Now how much difference would it make in my 106, would it be slight or very noticable?

 

it would be noticable below 3000rpm's

 

Too slight to worry about On a toruing bike. You won't notice seat of pants. If you were drag racing and needed another fraction of a second, then do it.

 

Get a stepped true dual head pipe! These headers can perform as good as a 2-1. Plus they sound and look a lot better. "They" will always say that 2-1 is so much better cause "they" don't understand the new head pipes. I don't have anything against the 2-1 but the true dual will always look and sound better and performance is not an issue as long as you get the right head pipe. Check out the MGS true duals!

Too many weak weld points on the 2-1-2 for me!

 

I would like to see some proof of this, true duals having the same torque as a 2-1 I don't see how?

 

"These headers can perform as good as a 2-1"
Yeah, if the 2-1 bike isn't tuned properly!

"They sound and look a lot better"
I do believe sound and look are subjective. DO you have any data charts to back that claim?

""They" will always say that 2-1 is so much better cause "they" don't understand the new head pipes"
So, the manufacturers and the test personnel that have proven over and over what performs best don't understand the new head pipes?

"Too many weak weld points on the 2-1-2 for me!
Yes, I heard on the forum they're all falling apart everywhere, littering the streets!

 

Thats funny
