Exhaust Question for my '64

[javadoc]

I'm bouncing around a lot of my 'to do' list, and one thing that I did not do correctly when I put the 383 in my truck this past summer was do a good job installing an exhaust on it. I'm running headers with 2.5" outlets, and all I want to do is dump the mufflers out the side, in front of the rear wheels. However, the angle is of course canted back at a few degrees angle.

So the question is, is there a simple (in my garage) way to get the angle moved back to level? I do not weld (I'd like to learn), so I am looking for a bolt-together solution. Will something like a flex pipe work? I'm open to almost any idea, that doesn't make me go to the exhaust shop for such a simple layout.

Looking forward to your input!
