It would do you wise to research the topic, instead of trusting a salesman.

I have.

Akra posits what 7-8 HP increase, and were talking tune dependent at that.

There's nothing to suggest that it is tune dependent.

Termi states 5% increase in power, that "could" translate to a hair more.

So this 10+ HP claim is more believable?

There are people on this board, that have swapped out there full termi for a Akra. These peoples subjective and possibly biased opinion, I actually trust more then company claims.

A forum post about what feels better is hardly subjective data to make a comparison.

Because of the custom tune required on the Akra, any subtle difference or improvement, is now a subjective claim, as we are not comparing apples to apples.

What custom tune are you talking about?

Unless, those who have kept the full termi upmap key, and added the Akra.

Why would you take a map designed for one exhaust and use it with another design and assume that would be the most ideal solution?

NOW if someone has done this please step up and share your thoughts if you have ran over 6 months with each exhuast.

I think you should go back and re-read my post when I wrote about the different trim values for Akra/Termi maps.

Look at the mapping and see if nothing stands out which would suggest some optimizing on the part of Akrapovic to make the most of the stock maps.

I'm very suspicious of any dyno chart I see posted here. Most look like something someone whipped up in MS Paint.

But also according to Tuneboy, the full Akra adds significant increase of torque in midrange with almost the same max power (Red: 1199 with Full Termi and Tuneboy map; Blue: 1199 with full Akra and Tuneboy map):

if that is what Tuneboy is reporting for termi after tuning then they are doing a very poor job. I have a full termi with rapidbike and buttdyno says the mid range is much much better than that. not to mention those crazy HP numbers...
 
is there a way to add the stock dyno to that chart for a comparison of the 3? I am very curious since I am considering dropping more $$$ and want the most bang for my buck. I care very little about the up top numbers but the midrange bump is what really would matter the most. Thanks!

Nonsense.

Which stock map? the one termi did for the full system?


It is not designed to throw on a bike and enjoy out of the box. That is a waist of money unless you want to spend 3G's on sound.

No aftermarket exhaust system is ever meant to be added and not tuned to the bike.

Dude if you're not going to read and make at least a token effort to comprehend what I'm typing...

Look at it in reality.

They are both good exhaust, and are both very close in performance.


Not one will give you an edge on the track over the other, because they preform so close to one another.


Akra cost more, but looks a little nicer, build quality a hair higher, and reported that the sound is nicer.

Without a custom tune it will not outperform the full termi with upmap key.

With the custom tune, you can adjust the midrange dip on the Akra.

Both have pro's and con's, but in the end, they are both good products

I can tell you that my bike on the same dyno went up about 10 nm around the 5k range. From memory complete OEM stock it went from 75nm to 85. Can I tell the difference when riding. Yes I can. Big time.

When I went from stock to Akra without the tune, could I tell the difference? No. Just the noise. After the custom tune, yes. My 2 cents.
 
I'm no expert. But doesn't Akra with more exhaust flow than stock run lean with stock map?
And lean gives more power at expense of the engine safety margin?
 
Thanks for the info.

I'm liking the idea of the Rapid Bike option.

The only bummer is having to play with a MS OS again.

I have had enough with the HEX CAN stuff with my Audi. Might have to do APR Mobile.
 
That is gonna be the plan if I can't get the others.

The local powder coating shop does the thermal stuff and I was thinking of getting the aluminum plates coated black like the 2015's have now.
 
The new forward exit Carbon Termi cans look like being a winner.
I notice there's huge improvements in the advertised power curve.
It appears as though there's an air filter with the new slip-on kit as well.

If this was out at the time the 1199 was revealed, I should imagine it's the system we would still be using as the yard stick.
Seriously considering swapping my Titanium Termi slip-ons for the new design:)
