Here's the way I do it. Buy a few pre bent pipe, cut em apart (I used a saw all) and put them back together again the way you want them. If doesn't work the first time try it again. It's just metal. My header came real close to the crossmember so I had to make a couple of sharp bends to make it work. I think it came out pretty good and it was kinda fun too! Sorry, no welded pics but I used flux core and it didn't come out too bad IMHO.
