I do have one of these tho not from this seller, ive had mine on for best part of two years and im fairly happy with it. Sounds great but the fitment dose let it down abit, in the end i had to get a mate at powerflow to mess around with it to get it on and even now it still sits a little lower then i would like. I paid £410 for mine so price wise im quite happy with it to say its a full true dual inc y-pipe whereas the k1/k2 are neither.
