At the Advance Auto Parts the other day I was there, I saw that they now have flexible exaust tubing. It has a design similar to that silver duct-work tubing you see kids stick on their arms when they pretend to be robots. It's a bit more expensive than normal tubing, and it might not have as good a flow as a normal tubing with all the flex grooves (since I really had no interest in buying any, yet at least, I didn't really examine it to see if they had a covering the inside), but as you might imagine, it's a lot easier to work with. Just bend it like Gumby where you want it to go... Might have been a little less complicated than that weld job.
