wavrdr I don't have the graphs, but can get them. All dyno units are only relevant to that dyno before and after.

FWIW:
My 13' had a Hanshaw built super sport engine
Degree'd cams, thinner gaskets, stacks, kit stator, PCV
The arrow made 125.9/52 on MR 12
The Akra made 128.5/53.6 on MR 12 in a 5 degree warmer dyno room vs the first pull

The Akra unit is far more efficient as we had to pull fuel to hit target afr. In addition, no middleweight bike has ever dynoed that high on that unit. Most SS built GSXR 750's on Mr12 make around 129-131 on this particular dyno.

It sure is more cost efficient than getting a supersport engine build though and a very nice gain for any supersport bike with those mods.

If you want to improve the performance of your Arrow shorten the canister by about 6 inches. The system's overall length is just too long. (you can see what the Smith's team did with their Arrow systems in the UK)
Right on.

Depends if you're going to be racing or not....but I agree with what you're getting at.

This hp figure seems to be inline with what the rest of these bikes put down in stock trim according to a few magazines and online reviews.

Modifications were installed with 1500 miles on the clock. Include: full Akrapovic titanium exhaust, Triumph factory flash tune, PCV, Driven block of plates, stock filter with mesh screen removed. Installation and tuning was performed by former AMA Superbike rider Mark Ledesma at Go AZ Motorcycles in Scottsdale AZ.

The final result after 3 consecutive pulls was 125rwhp. We were all very impressed with the gains and were not expecting such jump in power with just a full exhaust and tune. Even Mark, a seasoned veteran, was skeptical of the hp gains advertised on Akrapovic's website. Fortunately all our doubts were put to rest. The Akrapovic system is truly a work of art and definitely worth the money. Just wanted to give a shout out to Mark at Go AZ Motorcycles for doing excellent work along with Akrapovic for building such an awesome exhaust!












Gorgeous bike dude. Well done. Exhaust pretty easy to install?

I remember you saying that and I believe it. I was talking about the Arrow vs. Akra because I know Alan's bike had the Arrow beforehand. Believe me, I think Akra makes the best exhaust out there but Arrow makes pretty good stuff.

Yeah, I'm thinking the dyno where it was tuned may read a little high. It dynoed at 119 prior to any tuning. This is a stock motor with the race ecu, harness, BMC filter, 93 pump, and Arrow full exhaust. I wish we had stock bike graph on the same dyno.
