Been on the forum long time; I have a original Gen1 Hayabusa I bought in '99. I did some mods to but nothing extreme.
With the Gen1s a good mod was GOOD exhaust system. I put on a Sato racing syste. Gained power across the band. Actaul noticeable power on dyno. IIRC it was about a 10hp gain up top with no mid range loss. I still have the bike, but is sits mostly and really hasnt been ridden much since mid 2000s.
Now I am old. The sport bikes are just now uncomfortable to ride. I bought a big ADV bike, but they just dont have the speed and handling of sport bikes. It is OK, but then rode my Hayabusa some. I needed that feeling. So I happened to run across a B-king.
I have not gotten into the airbox, but I doubt the Bking has a modified airbox. It will need that. It does have a dominator exhaust system on it, but the cat delete was not done.
How much difference in power is there with and without Cat?
My plan is airbox mode, get rid of servo, ECU flash. Debating if i should do cat delete. If it is one or two hp, not worth it. If getting rid of a cat opens up 10hp it worth it. It does drop some weight.
On a crazy question, has anyone modified a good hayabusa 4into1 header to fit a Bking? I like the looks of the aftermarket exhaust under the seat. I dont like the new style of short mufflers or the "sidewinder" type of exhausts (brocks). They just dont look "finished" to me. But not sure if a 4-1 header put into the undereat exhaust would be any real world power. It might be a little lighter.
