flex pipe
A lot of people (manufacturers and 03lances) have been putting flexible piping in a small section of the downpipe or extension to avoid breaking. Are you going to have this done? Also, if anyone else wants to chime in on what flex pipe they think should be used that would help, I hear the stuff at autozone is garbage and will leak very quickly after install.

Nice catch
you dont need a flex pipe, what Im running is a stock downpipe, with the evo 8 downpipe bolts and springs, basically when your motor moves from the accelerator, the springs act a flex to prevent anything from breaking. You can always buy a flex pipe but if you want to stay the cheap route just do what I did. Either option is good
I also want to put my wideband o2 bung there too, so that no matter if i replace the pipes, no more exhaust welding.

That's right, there are springs! So, when you cut it (since I'm lazy and haven't measured) do you cut before or after the 2 bolt locations? Like, do you cut just before the flange to extend or do you cut just before the bolts and extend. My hope was that I could actually make a second piece of pipe, kind of like a test pipe, and just put that in place. That way, the stock downpipe stays in tact and the cat stays in tact, so either can be replaced easily down theline.

On the test pipe, maybe just get 2 flanges and a piece of pipe welded to the right length....and leave the test pipe in-tact, you could resell it or use it if you ever go back to stock.

I had this same question. I would think the first o2 sensor would be fine, but the second one would complain, due to absence of the cat where the header now is. Aside from that, I think you'll get CEL's from a bad tune, too lean, too rich etc.

depends i guess
Also, you aren't going to pass inspection if they stick something in your tail pipe I don't think. Some places do, some dont.....in texas they do.
*edit* oh snap, you're in california right? I'd think you have no chance of passing there, don't they like "white glove" test the car out west? too worried about the trees and what not?

You're going to get "cat efficiency" errors I think, like....p0420 or whatever it is.

im in texas, and all they do down here is just plug a computer to your car and run it just to see what they flow is etc... I got a friend that can do it so im not to worried I just dont want to run into any CEL errors because I have no second cat under the car and no CEL came on
