Arrow GP2 Slip-On

[elecante]

Hello all, I have a pair of Arrow GP2 Slip-On lying around, so i figured i'd do a custom fit on my bike, I have been trying to find a link pipe for them, but no success. I love the sound of the exhaust and really want to install them on my bike, inlet of the exhaust 54mm and outlet 58mm, would appreciate if i could get some pointers as to where i can source the pipes. Txs in advance.
