This guy is selling a greddy sp2 axleback, he wants 150 for it. Bad thing about this axleback is that its off a totaled gsr so there is scrapes on the bottom of it, he says that the muffler didnt get hit, that it just dragged along the dirt. when you shake it, it seems like theres a tiny pebble in there. What do you guys think?

 

if it is a pebble it might come out if you shake it vertically, if it doesn't then its gonna rattle
