I ordered a j's 60rs stainless steel through a local tuner and picked it up I think back in February/March some time. I've finally decided to install it, only I just realised I don't have any bolts or washers or gaskets etc. Does anybody know if I was supposed to get these with the exhaust or do I re-use the ones from the factory exhaust? When I picked the exhaust up, I left the box there and only took the exhaust, but I'm pretty sure I took everything that was in the box.
