Thanks for ur input fellas,
Im still unsure, over $1000 on headers. I need to know for sure but can't get a definate answer. So my local dealer told me
"Yoshimura is manufactured in two different countries, that being the USA and Japan. Same brand, very different products??and prices. USA have no full system where as you can get a full system from Japan. Will the headers, which are not listed as a separate part, fit onto a USA manufactured muffler? More than likely not. Why don?t the USA make a full system? Because they probably didn?t gain enough out of what they manufactured OR the standard headers are good enough for them."
The serco the australian yoshi supplier told me "Thank you for your interest in Yoshimura products, unfortunately Yoshimura USA only produce a slip on for your model."
Then I was talking to a company in the uk called calsports they told me "The Yoshimura headers are for the R11 only I'm afraid, if you have the Alpha
then these won't work with that end can"
"Yes the Alpha fits the stock headers. Yoshimura themselves sell these headers as only fitting the R11. You?re welcome to purchase these headers with the understanding that they won?t bolt on to your existing end can and would be non-returnable. "
He then replied after me making a few comments,
"The headers do away with the link pipe on the R11 (it uses this to attach to the OE cat box), the Alpha has a welded on link pipe ergo they will not work together."
I mean, all this just doesnt add up. I have never put aftermarket headers on a road bike before so this is a bit new to me. I need some advice and help here
