That sounds absolutely fantastic
I recently picked this used akrapovic up from webike.japan, it only cost me 170 pounds (200 ish dollars) and well being titanium its waaaay lighter than the original + it polished up nicely (it needed a lot of help haha, hence the price). Now it looks very very nice i think, i'v ended up giving it more of a brushed aluminum finish, but i dont mind. Yet to fire it up, i am stoked to hear it with + without DB killer haha.
