How much pipe (length) for a custom exhaust?
It looks like its going to end up costing me about 220 including 3" cat, resonator, and muffler altogether. If I cut the cat and the resonator from the equation, I would be saving myself over a hundred bucks. However I dont wanna mess with my exhaust when I go to smog the car this next april, I should have enough issues for that as it is.

Umm...I use about 1 foot after the cat, to a slight bend, to some more feet, to a few fancy twists, to the muffler, then the tail pipe. I'm pretty sure I use the entire 180 bend out by the muffler, and a section of the 45 bend half way between the muffler and the cat.
My downpipe goes pretty far back.
This is all 3 inch. Smaller pipes could be done easier, and aluminized does last a very, very, very long time and welds very easily.
I tried to fit Y8S' 5x11x22 in there but couldn't figure it out
Fortunately the 5x8x18 (canister size, not overall) with no resonator is relatively quiet. Pics of my car, 5x8x11 magnaflow:

For turbotim, since your pm box is full ...
sorry for using a thread for this, but at least it is relevant 
I was wondering if I could buy a couple things off of you through shore ... I basically just need a few things for my exhaust im going to weld up in a few weeks. I will need two 3" 2 or 3 bolt flanges and a 2.5"-3" 2 bolt pattern with adjustable bolt spacing to mate up to my begi downpipe ... or if you know the bolt spacing, a matching flange would be just fine. Then I need a few weld on hangers. Also if it wouldnt be too expensive, a few non-mandrel bent 30-45* 3" bends to do the first part of the pipe (I bought a mandrel U bend to do the 90* turns, but thought it overkill for the smaller bends).
Also, i know it might be a long shot but I am also looking for a 2" 90* silicone coupler and some tbolt clamps.

About $900 to ship your car to the east coast, another ~$800 for the exhaust installed, and another $900 to ship it back to the west coast.

lets see... turbo back following the stock system looks like:
90° for the outlet (smaller diam + reducer)
90° for the bottom of the downpipe
15° for a kink at the tranny
6-8" of straight from there to the cat
18 inches of straight for the cat
6-8" of straight from there to the kink
another 15° for another kink half way back
6-8" of straight from the kink to the resonator
18 inches of straight for the resonator
a few more straight inches to the diff
about 45° and 8" for the kinks at the diff
90° to exit the diff space
180° U to turn around to go into the muffler
whatever you use for the muffler
and a 90° to exit the muffler
a shiny chrome tip the size of a grapefruit.
I think I used 3x 3" U bends, a 2-1/4 90° for the turbine outlet, a 2-1/4 to 3" reducer, a 3" 90° for the muffler outlet, a 3" cat, 3" "bullet race" resonator, 3" magnaflow muffler, and 3 feet of straight pipe (give or take). plus the tip. there's enough straight on the U bends to fill in the rest of the straight space but extra straight pipe is cheap and easier because it's not squashed from bending.
