Hi Gents
thanks for the reply Stil and Jepp, the IXIL is a great sounding pipe as shown on your vid and I was very close to making it my choice, the SC is a nice looking pipe also.
However following a chat with the dealers, they offered me the Akra Yamaha official version for £790 plus if needed fitting . following negotiations I have gone with the Akra , I have managed all be it a small victory to get the price down to £700 with Fitting and more importantly the engine mapped for the exhaust with no db killer fitted.
the price for the pipe to be fair I still feel is dear compared with alternatives and especially the IXIL, however the snobbery played it's part, but also the guarantee that this addition would not effect the warranty should the very unlikely engine failure occur.
we make decisions we live with and in this instance I was able to pay the extra for the overpriced Akra and I am sure I will be as happy as you all are with your own choices.
so on the 1st of March I will receive my Moto Cage with R&G Tail tidy, yam LED's and the Akra, and I can't wait...it's a shame you have to run the engine in
