That is different, how loud is it (with the 3 baffles in it)??  Comparable to the yosh?  I have never seen that before, I have ridden around the block before with out the silencer on before, man that was loud.

...It is not as load as my old gsxr1100 which was fitted w/a yosh pipe......it has a bassi rubble at low rpm, it does wake up at throttle, put it this way I probably wont be goosing it in town any more.....:42:
 
<span style='color:red'>not bad... but i had something else in mind...my plan is to make it like the buell exhaust .....or maybe get a buell exhaust and shorten it hollow it......</span>

....interesting idea....the only thing that would concern me would be, flow characteristics, the buell being a 2 cyl. verses the busa 4, the size of inputs and how many, also the volume and output size.......building mine I tried to keep volume and output size the same, not wanting to remap, keeping things as simple as poss......160 bhp is plenty for me.::r{{
 
<span style='color:darkblue'>You are right... thats why you remove the baffles .....all you want is the can....or half a can...run the straight pipe into the can....i think i might make one & post a pic...

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?
 
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.
 
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?
