Strap it to a DYNO!

Looks good just curious what kind of Power Gain/Loss you received?

?

Do you think it has enough back pressure without hurting something for street duty?

Thanks....power is up....throttle response is increatible.. I have also added TRE, air box mod, air filter, and removed air injection...I have been riding for 30 years, this is the bike I have been trying to build for years.....when building the exhaust I tried to keep volume and output pipe size stock, therefore back pressure should be ok...I was not looking for more power....but for the look and weight benies....

I would think that without a visible can you will pulled over by every cop you come accross, especially if it is even marginally loud. I guess it would be no different than a Turbo'd bike with a dump only. Very different though, my hat's off to such ingenuity.

Well, that is a perpective I did'nt think about

the pipe is more visible in real life, than the pictures show....also I suppose if a cop does see the bike and hear the throaty, low rumble of the pipe, he may think that it is a standard 1-4 pipe, you can only see 1 side at a time...unless of course he is right behind me......I think we will be seeing more and more of this kind of system, KTM, and Buell already have such systems....

Looks good. I would think you could loose HP on the Mid RPM's?  what did you notice on your idle RPM's when you made the change?

Thanks....power seems to be up thru-out range very linear, I will know more as wheather improves and I can really ride hard, I just completed 3-4 weeks ago, have only had out 4 or 5 times.......
