If you're making your own bends and flares stainless is a bear to work with. I used a coated tubing from Advance Auto, I think called ArmorCoat or something. You get a big roll of it pretty cheap. I've done everything except across the rear axle so far.

For the bling factor some guys will go with the zinc coated standard stuff, polish with scotchbrite and spray with clear lacquer or acrylic.
