My exhaust is SS dual from the headers back and goes into a dual in dual out muffler. It has different tips then stock. Pics are in my gallery.

When I got my exhaust the price was $1,200 for R&D and assembly. I'm hoping with the R&D done already that reproductions can be had for around $500 - $600. 400 seems unreasonable unless the volume is extreme. I don't even think that the cat backs we have now are that cheap.

As far as the intake, dual filters alone will cost about $80 - $100 depending on quality. The piping, ducting, clamps, etc. will also add up and bring the cost closer to $200+.

Like I said, if there is enough interest we an get this thing going. If at least ten people are interested in both, I'll start pricing and go from there.
