There is an exhaust company in Spokane WA that is trying to get a hold of a 06-07 zx10 for R&D for a new exhaust. I was looking on their website and couldnt find exhaust for the 06-07 zx10 so I called and he said they get calls all the time about this but do not have a bike to do the R&D on. If you live in the Spokane area and would be interested in letting them use your bike the guy said that they would give you the exhaust at cost and wouldnt charge labor for putting it on. Anyhow the website is www.hardrockmotorsports.com and all their contact info is on the website. Grant is the name of the guy I talked to. If only I lived in Washington I would do it but unfortunately I live in southern Alabama. I am really interested in what they will come up with and just thought I would share with the rest of you.
