Hey Flight, Dezzy pretty much summed up my POV exactly. What real use do you have for 10-12 HP? If your allways on the 1/4 or amatuer Road racing OK, otherwise, just for looks and sound.
This is why I just wanted Bolt-Ons. I rarely use "EVERYTHING" the Busa has to offer anyway, so besides the occasional Bridge blast or weekend twisty attack I just don't really see the justification. Although Weight loss is the other consideration, it would be nice to shave 20lbs off the Busa, and a dyno won't reflect this, but your real world living with the machine might. Unfortunately it lops most of the weight off the bottom and centerline, so it's not going to dramatically improve handling though there will be less mass to be grunting around in parking lots.
I love the sound of The Akropovic Carbon Bolt-ons and they look perfect, like they were designed for my bike specifically. The quality is also impressive, very well finished. But, Akro is really damned pricey, if you can find a set used that would be the way to go. Micron does some really good things with their pipes and from what I have heard are responsive to customer needs/problems. They were my second choice.
Volume wise the Akro's aren't bad at all, a good bit louder than stock at idle and low rpms and it's a nice deep noise, then they are actually not all that much louder than stock when FWO out in the sticks. Louder than stock yeah, but the stock exhaust starts to scream a good bit at the high end too...
Over all I am 100% satisfied with the Akro's, they look good, sound good, took 15 minutes to install, and they are quite enough that I don't feel like a punk kid when I am rollin into my neighborhood at 2AM. BUT, No real power gain, like I said a couple maybe, and about a 8-10 lbs drop in weight, (Stock Cans are fugging Beefy)
PM me with your email addy and I will email you with an MPEG of how the pipes sound on a busa. Loboboy hooked me up with it when I bought mine from him...
And finally... Just cause I can, lemme splatter these tired pictures on the board again...
