Well guys first off I have to confess, I have no Hayabusa. But I am a Suzuki fan. I love old suzuki muscle. I own a 1981 Gs750L & a 1985 GS1150. I can really appreciate the new bikes, the lines are slick, smooth and sexy, but the speed and riding position do not interest me. The relationship between the old Kantana and the lines of the Hayabusa are defintately there. No the reason I joined was to check out the bikes, banter, and ask a question. It's a perfomance question. I want to put a header designed for the the 06 busa on my 1150. Does anyone know if the head pipe matches up to the exhaust ports on my classic muscle? If it does, I'm looking for a Muzzy headpipe. Thanks guys for any help. I hope I don't get flamed too bad. and since everyone likes pics, here's my 1150:
