Yeah, I ran Samson true dual fishtail exhaust.
Yes, loved the look, loved the sound. But they ARE NOT the best choice for peak power numbers.
If your looking to create a dyno sheet to brag your numbers on, switch to a 2 into 1 system. And you'll be right at the figures your seeking.

Here's an example..
In 6th gear:
Stock 32/66 combo at 80mph = 2936 rpm
With 32/68 combo at 80mph = 3025 rpm
With 32/70 combo at 80 mph = 3114
With 30/68 combo at 80mph = 3226 rpm
With 30/70 combo at 80mph = 3321 rpm

Where the hell did I say 14 horsepower, or ANY number?
I just said a 2 into 1 performs better than true duals. And will get him close. Whatever dude.

A good 2-1 will get you around 7-10HP increase in power, I installed the Fat Cat 2-1 Pro exhaust with perforated baffles and she flies, increased my ride by 10 hp so worth it for me. Sounds pretty good too.

If anyone likes to know numbers, as riding after any work is not easily measured, it is always advisable to ask for a Dyno before any work, it's just a way of keeping a measurement for current builds and future add on's. Usually, if you talk nice to the shop, as they are also interested to keep records, they will do the second run for free being an advantage to them as much as you for future reference/customers.
HD really do not like giving out numbers, especially when a lot of the stock bikes at barely reach the high sixties in HP.
