R/B header
Well they're $187 brand new so if its new or it good shape you made off well. Well that header is not going to bolt up to your stock cat so you know ahead of time. You need the RB presilencer which will go from the header to the stock y-pipe. A cheaper route is just to have a muffler shop make you a straight pipe, but it will be loud.
