Yep. ECU-boost is allowed in SP. I believe the solid motor mount would also put you in SP, although the latest Fastrack proposes loosening that rule a bit in ST* classes.
Granted, a fully prepped SP car can be practically un-streetable... but a lot of regions are running SP-Street Tire classes for guys running cars not quite so heavily prepped.

i won't do that cause i have a warranty still on this car and when i go and buy a down pipe it will be catless so that alone throws me in a higher class.

that is good, now i just wish all this stuff wouldn't put me in such a high class since i won't be making it a strictly auto x car. i'd rather end up in a ST class since this car won't ever see slicks.
Lots of regions are running an index for street tires in a class where R-comps are allowed. In our region you put a T before your class designation.
Brings some sanity back to the whole "R-comps in Stock Class" debacle.

My car had a cat. The two are not mutually exclusive and an exhaust pipe is going to be more warranty friendly than an equivalent to beyond stage I computer upgrade, I'd think.

I wouldn't worry about it if it's not going to be a dedicated race car... mod it how you want, and just drive it in whatever class it falls into. And of course, have fun. 
yeah... I didn't care so much about modding my car to the Nth degree when I was running my TDi or MINI 'vert... but the worst thing you can do is to buy a car specifically for auto-x only to find out afterwards it's not the best car in the world for such use... research:fail on my part...

i don't need to upgrade any piping for awhile on this car maybe go to a better material later on, cause stock it has 3" piping. there are 2 restrictive cats. they are rather large, and hindersome.(if i could post a facebook picture i would since that is all i can find in regards a picture.)
Catless downpipe? Why?
I really don't understand this anymore. If it was 1975 and catalytic converters were causing vehicle fires, extreme backpressure, horrible smells from the exhaust etc etc I would understand it. It's not 1975 anymore. Plus, isn't this like the SRT4 Neon that didn't use a muffler, just the turbo and a cat setup for reducing exhaust noise? If that's the case, you're going to what, remove the cat so you can install a muffler?

no it is not, my car has one really big cat then one normal sized one, then back to a ridiculously huge muffler.
this is a picture of the stock muffler and why i am wanting to replace it.
which i am going to something like this
this is my down pipe/o2 housing the one on the left side is my o2 housing the other one is the rest of the downpipe.

Don't bother with the two mufflers. That's just extra weight and no performance benefit.
I used this on my WRX in place of the muffler:

On the car photo (this one is my car) - http://farm6.static.flickr.com/5108/5650407496_993c87db66_o.jpg
It was about $50, took 30lbs off the car, and sounds damn good.
ya i couldn't deal with that, but the down pipe i am looking into has something like that just a electric cut out.

Couldn't deal with it because of sound? I have the stock turbo, stock cat, and stock resonator, and the turndown makes it sound like a performance exhaust with zero drone. Not loud at all.
I had a turndown on my SRT-4 as well, and while it might have been a little louder than my WRX, it was no where near as bad as most cars that buzz past me on the highway.
