I have a crack in my y-pipe, that I had welded before but now its cracked again and it extends up around the top of it. So I'm just going to replace the thing. Any particular brands I should look at, places to get a good one cheap? Summit has 2, hedman and edelbrock, both 3" and around $120 but I don't know which if either are better if theres even any real difference between y-pipes.
