Default Best headers
For someone who already has a stage II kit installed with SE 255 cams, what would be the best header to get that is not a two into one setup. I think I am going to get a new (better) dyno and am weighing the cost vs. performance improvement of adding a header. Right now I am at 85hp and 105tq.

The reason I want the bike re-dyno'd is my fuel economy averages 35, even at highway cruising, and I should be at 40+ with my setup.

Thanks,
mikebaby

I don't have any numbers, BUT, I do like the fit, look and sound of my Cobra Power Port Dual Head Pipe...

Here is their website:

Cobra Exhaust

Here is a write-up from Bagger Mag

I have photos of them on my bike and vids of the sound (link in the sig).

The price was pretty reasonable too, specifically through direct harley parts...

What kind of tuner you running, sounds like you may be fatt in a few areas. If your running a fuel manager, contact Fuel Moto for a map, I betcha they have one for your setup.

I'm running V&H Dresser Duals just because I like the look. They sound pretty good too.

Looking at your dyno numbers, i'd be very surprised if you could get better performance out of different headers. I also have an 09 Street Glide. With a simple stage one my fuel mileage average was 35 mpg as well. Now i have a 107 build and still getting about the same mpg. I'm not sure what the difference is with these guys that claim 40+ mpg after a build. My advice: Forget the numbers. If you are happy with the bikes performance then leave it alone. You could spend a lot of time and money chasing those few extra mpg and wind up with nothing better than you have now.

It is not the add'l I am chasing as much as the additional 30+ miles per tank, which on long trips is nice. If I am getting a new tune, and headers will help, why not?
