Exhaust help needed

[ninjak84]

I'm buying an APEX'i N1 muffler, but I'm planning on doing a full exhaust set-up myself. I want to replace the current pipe (from the catylitic converter and on) with one that is larger. So basically, I want to weld the new pipe to the muffler and go from there. What I need to know is:

- What kind of pipe do I buy? It absolutely HAS to be rust proof- How big should it be? 2 inches? 3 inches?- Where can I buy it?

Thanks!

2.5" should be suffice on the piping size. Any muffler shop should have it. Just make sure they can do mandrel bends when they make the piping.
