So I'm redoing my exhaust 2.5 in the whole way. Pacesetter headers into H pipe into thrush glass packs. Only thing is I have these rusty 1 3/4 pipes coming off the headers because I can't find an exhaust system that goes from the headers back. Is there even such a thing? Or do I have to bend my own pipe? I didn't want to leave the old 1 3/4 on there because I feel it is restricting flow and I was thinking there's no way that a shop would leave those on there if you brought it in to have it done. Any input would be greatly appreciated thanks.
