Default Which Full Exhaust makes the most Power?

So like a lot of the other threads started on this forum hopefully mine is different. I would like to find a "deeper" sounding full system for my bike. But most of all which one makes the most power on the dyno?

You will get all kinds of claims to the best power on the dyno. It is hard to say, even looking at dyno sheets dont tell you much because it is a different bike at a different dyno with lots of variables. I like the Brocks for a deeper sound and good power increase.... Also the Austin Racing has a nice deep sound I hear and good power increase. Arrow is another one that comes up often. Only one I have experience with right now is Brocks but I am trying to find a way to get my hands on an Austin Racing GP3.

I can tell you that Keith Code's California Superbike School uses the Graves exhaust on their school bikes. He seems to think they're pretty good!

For the deepest toned soul stirring sweetest sound with best looks,none of the systems match the Taylormade,but it sure doesn't give you the best performance output,nonetheless a significant mid range improvement though.
For a reasonably deep and loud sweet tone plus max power output,you should be looking at the Akrapovic Race Shorty IMHO.

Default Best power

Just my opinion, because its hard to sort through the bullshit marketing claims i just referr to what the racers are using. Here in the uk in the bsb they are using Arrow full ti systems so they must be good right ? I know there are sponsers and that's probably why the world super bikes use akrapovic systems. The truest indicator i believe is to see what the independant and the super stockers are using and it's arrow. I have also spoken to an independant racer who says the arrow full works ti gives the best power. Even if hes wrong it must be right up there .

I have the Alienhead black. I like it alot. It sounds good, very loud but kinda deep (not as deep as the M4's on my ZX14 but that was dual exhaust and a 14), and at high rev it sounds awesome especially when WOT shifting. It may or may not give great power. I haven't put it on a Dyno yet. The support with maps and such is really good. I filled out the form and had 3 maps sent to my email the next day. One for street, one for track, and one hybrid. The system is full SS but the whole thing is ceramic coated black so it looks great with the red bike blending with all the black at the bottom.

Our full Inconel system in GP3 or long exit pipe makes the best power in tests on the BSB dyno vs the Arrow and Akra systems. We hit 201BHP on Joe Burns superstock bike.
In the UK race bikes use Arrow and Akra as they are either free or heavily discounted to racers and teams. As a small company we are not able to do this.

At this time Jon Railtons ZX10 superstock bike with our Gp3 system makes the best power and consistently fastest speed trap speed's at the Uk meetings.

We are always happy to head to head test if any owners dispute any of the above info.
