What parts to get for new Redline?

[MitchMeister-]

Hey people,
My names Mitch and i just started working for Saturn of Greenfield in Wisconsin. Today was my first day, and we got to test drive all of the models we offer. Well, i got to take our new black Ion Redline with the compition package that had only 9 miles on it. Obviouslly i didnt beat on the car, but i did take it out and had some fun. I was thinking of purchasing one before i drove it, and now i really want one. I've been looking all over this and other forums about what parts i want to get, but i really dont know. I've owned 2 trans ams and a firebird so i know gm v8s more than a 2.0L DOC supercharged ECOTEC motor. So i had a couple questions... (i plan on ordering my new redline sometime before xmas, depending on how my sales go)...
1.)What exhaust is the best to get for this car? My number one thing is that it cant sound like 'ricey' civic big ass can exhaust. I hate that, especially coming from a t/a with SLP loudmouth. Magnaflow sounded decent on their website.
2.) CAI? I assumed K&N were the only makers currently until i saw the others. Whats the best?
3.)My friend owns a Cobalt SS and wants to buy the pulley puller and the 2.9" Pulley. I know u need new plugs/wires (i plan on getting HotWires and their Silver plugs) and the ECU reprograming (which does or does not exsist from what ive been reading). Will this really be a noticable jump in HP?
4.)Where to get bigger injectors? And how big?
5.)Headers? CAT? Whats the best to get?
And what other mods/parts do you recomend?

Also. . . can you hook up another Amplifier to the stock deck (MP3, XM, 6 disk option)? Because i dont want to pay for the option if i cant hook up an amp. Also it says that the speaker upgrade are connect Coax... so can you even replace the stock deck?

I know most of this will be very opinion based, but if someone who has most of what im asking could post links to the parts (or at least what they are called) and tell me what HP your getting.. it would make things much easier for me.. (and possibly other redline owners).

Thanks...

full cat back custom to fit your wants and looks. Any exhaust shop can do this.

torque brace. Wheel hop is evil 100.00 and your cured

short shifter. only one out there so get it.

Drop it some. Springs range from 1-3 inch get what you like. I got sprints 2 inch and loved them.

2.8 inch pulley and larger idler would be a nice addition. This should be paired with better plugs wires are useless on this car. Coil on plug kinda makes it useless.

An intake in my opinion is only for sound. And with the smaller pulley its going to scream get it and be happy.

these are in the order I would reccomend.

Are you getting an 05 or an 06? If it is an 05 you should be able to add an amp to the factory stereo (I would think this would hold true for an 06 also). All you need is a line converter (SNI-35 from PAC) and an amp kit + RCA's. To replace the stereo you can buy a wiring harness that will allow you to use the factory wiring harness. May not be available for 06. I wouldn't get the premium sound if if is not already installed as you can get more for the same amount of money at a stereo shop.

By idler do u mean a larger bore throttle body?

no, meaning get a smaller 2.9" pulley but also get a bigger idler pulley so that the stock belt will still fit. You need to even it out.
