Setup in progress: 14b, 8 psi, DSM SMIC, going to get 42# or higher injectors and a bigger MAF along with a XCal II tune. Shooting for 200whp on a stock Zetec with just a 65mm tb.
Will I be okay sticking with my FS 2.25" exhaust or should I upgrade to a 2.5" or 3" exhaust?

I would go to 2.5" if ur gonna be running any kind of boost... 2.25" will work but u will gain a lot more with 2.5"... 3" is something for around 15psi+

I would at least go with 2.5

What are you guys using for exhaust, mild steel, aluminized steel, or stainless steel?

go with stainless if you can although aluminized will be ok it'll just rust faster.

Ok, cool. I'd like to go stainless, but aluminized is $6.50/ft cheaper, so I'll probably go with that.

I think if you're going to upgrade from a 2.25 you might aswell go 3" it won't hurt anything just be a little louder.

I had actually planned on it. If I couldn't keep my FS 2.25" exhaust I was going to go 3" just because I plan to upgrade the turbo setup later on down the road when money is less of an issue.

I don't know how big of a difference this makes but i used aluminized (of apparent reasons being cheaper) and then sprayed the whole exhaust with a couple of coats of anit rust exhaust spray...comes in various colors...so far i had bare pipe showing and this painted pipe...and only the bare pipe rusted a lil. So i cut it off and put in a different piece and painted it...no rust
