Exhaust size and material?
I'm into the detailed planning stages for the turbo setup on my car. Setup is 99% sure going to be a T25 .48A/R with a BEGI manifold shooting for 220rwhp at 12psi. I'm trying to decide on the exhaust setup now. I'd like to stick with the BEGI theme and use one of their 2.5" (or are they all 2.75" now) DPs. I would love to use mild steel to do this, since it'll save me some money, but what's the word on stainless vs. mild? I'm willing to cough up the dough, but if it's not going to gain me much besides the bling factor (which I don't want under the hood) then I won't bother. The hundred bucks will pay for injectors, so I'd really prefer to save the cash.
Same question for the catback. The options are the Enthuza budget turbo or the standard turbo exhaust. One is mild steel, one is stainless steel. Again, is there a big advantage to SS vs. mild? I was leaning slightly towards the stainless here because I can get a 3" catback, but it's quite a price jump, $369 vs. $450.

2.5 is fine. 3 is better.
stainless beyond the DP is not really worth it unless you live somewhere salty or corrosion prone. a good aluminized will last until you swap exhausts anyway
if the DP is only 2.5, dont bother with a 3" cat back *shrug*

I am worried about heat with the T25 at 220rwhp. Sounds like I should look at a 2.5" SS Begi DP to a 2.5" aluminized catback. I don't think you can call Northern California a "salty" area, and no matter where I go for college the car won't be used in the snow.

You won't "need" anything other than a nice mild steel dp. If you are interested in how it looks and the length of time it stays together, then stainless might be worth it. I myself use stainless on everything I can, within reason.
