I bought this for my '05 Repsol, but I sold it last week and I am going to be picking up a new Gen 1KRR , so this will not fit it and I have no further need for it. I am actually disappointed I never got to install it as this Pipe is one of the nicest constructed pipes I have seen in my hands out of many Different brands of pipes I have owned and installed. Far nicer than the Last Yosh and two brothers pipes I had. I have no clue on the sound, but I know these were made by Arrow and expect them to sound very similar to those....so it should sound very good. It is a Titanium Piping and Can with a Carbon Fiber tip. It is 100% new in the box, never installed with every item that came with it for install. All is still sealed in the box's and bags they were shipped in. The pics were just taken and represent the item exactly as you should expect to receive it. The Item is Listed as fitment for an 06-07, but I ordered it for my 05 and after much research prior to ordering it, saw no reason it would not fit the 04-05 bikes. I will not gaurantee it to fit the 04-05 though as it is only "Technically" listed for the 06-07.....SO for the early guys..buy at your own risk. I am asking for $440 Shipped or $410 Picked up for this.
