What performs the best, head pipes with a crossover or true duels if the same high flow AC and mufflers were used on each? I like the look of the Jackpot 2-1-2 header much better than the VH crossover header. Is there a proven header/AC/muffler/tuner combination that makes the most power for the 2014 103"? Thanks for the help!

 

a lot of differing opinions here but the header systems that remove cat and go 2 into 1 have been hi on the HP gains. But alot of guys don't like the 2 into 1 look (including me).

So I would go with what "looks good" to you and do some simple research as far as HP gains. I personally like the Vance and hines setup for looks and sound but that's just my opinion for what that's WORTH. paul

 

I did quite a bit of research before deciding. The best hp gains were from 2 into 1. But like some others, I like the look of true duals better. However some true duals actually reduce hp. I chose MGS because I like the looks, the sound, and they promised an increase in hp. I did get an increase although not as much as I would have with 2 into 1.

 

Look at Fuel Moto's dyno charts on their Jackpot 2 into 1 into 2. This combo pretty much gives you the best of both worlds as far as I can tell. They have new charts with testing done on the new 2014s. I have this header coming this week for my 2013 Limited.

 

Just pick what you like and install it. Just make sure you get it tuned well so it runs correctly.

Unless you are planning to go to the track who cares what the numbers are except your ego.

 

Best performance =2 into 1

Less effective, but better looking = 2 into 1 into 2

Worst performance, but best sounding = 2 into 2

 

That's why I went with Power Duals. Kind of a compromise between the two.

 

2 into 1 - with Ghost Pipe (filler)

(here we go again) !

 

If I were going for max HP I'd get another Thunderheader, no ghost pipe why lug around extra weight that does nothing?To get the most out of it you need a good tuner and Dyno time $.Me I didn't want the expense or hassle of trying to get the most out of a stage one this time around so I went with a stock de-catted head pipe American Customs mufflers and baffles a Ness big Sucker and VIEDs at about a third of the cost, done.Sounds good, runs good, looks factory.
