I will be putting this catback system on my car in the next week or two. I was hoping you guys could give me a few pointers, the dos and don'ts of the install. I put my mid pipe on by myself and I didn't think that was all that bad. But any suggestions would be helpfully, because I am only 19 years old. Thanks a lot.

Are you using a lift or are you doing it on the ground? If you don't use a lift you will most likelly have to cut the stock exhaust off, I used a sawsall. 
I had to jack up each side of the car individually so that it would raise the suspension just enough for the pipe to fit over the rear axle, use wd40 to help slide the hangers out from the rubber, and make sure that you line up everything nice and straight or the exahust will slam against suspension or frame. The drivers side seems to be more problematic, I had fitment issues in both my 00 GT and 02 GT, I had to do some adjustments to get it to fit right.
Hope this helps.

You ready?
Front of the car up on ramps.
Jack up the rear on the pumpkin, place jackstands under the axles, lower onto stands.
Spray WD-40 on the hangers and bolts to the mid-pipe
Cut the axle-overs right behind the mufflers. They will slide out the back.
Unbolt the remaining exhaust.
Hard part. Magnaflow says do it from the mid pipe back
do it from the back to the mid pipe
Lower the rear of the car. Support the car by the body (body jack points) (Not for long, don't go under unless you have to)using your jack stands. You need to get the rear end to hang by the suspension.
The axle over tube for the driver side will go right over. The passenger side is the pain. You will need to loosen/remove the exhuast hanger bracket nearest the axle. The axle over should just make it, becareful of the abs sensors and brake lines.
Once both axle overs are done, resupport the car by the axle.
Slide the muffler onto the axle over and then the extension tube to the mid pipe Placing in hangers as needed. Install tips loosly into hangers and axle over tube.
Bolt the midpipe and extension together. Lightly clamp muffler to extension and axle over. The same with the tip
Now make sure that the exhaust is not hitting anything. You should be able to slide your hand down the pipe and not hit it on anything. This part can take the longest.
Once everything is where you want it start tightening down from the mid pipe to the back. The tip will need a little extra strenght to get it to start to compress on the axle over tube (once it gets tight keep going unitl the tip doesn't slide on the axle over tube) Place some lock tight on the set screw for the tip support rods and and tighten those MF's down (most pron part to loosen up)
Double check everything, lower and start her up . Let it idle for a bit and enjoy the new found voice
When you go for a ride bog the motor near a wall with the windows down (15mph in 1st, skip shift to 4th and romp it) If you here a tick you got a leak bring it back and try to find it. Go over some bumpy stuff and listen for banging, too.
Tip: Make sure that all the tubes are inserted enough that the cuts for clamping are fully sealed (you will understand once you see them)
Check it in a week for clamp tightness and alignment. If all good go and get it welded (unless you want it removable without cutting)
THEY will get louder as they break in, so don't be discouraged at first if it wasn't what you were expecting.
Until you get it on feel free to click my sig to get a taste of what you are in for.

It's very easy if you can get the stock cat back off. My friend cut it off with a torch for me. Putting it on was a piece of cake. WD-40 up the hangers when you want to get the exhaust off/on the hangers.

Buy the magnapacks for the perfomance. No chambered muffler can compete performance wise with a chambered muffler. Sound wise really depends on what you are looking for. I love the sound of my flows, I also like the sound of magnapacks though but not as much as my flows. You will never get the muscle car sound with the packs. Put some nice aggressive cams, O/R H-pipe, and flowmaster catback and you will have the true mustang sound.
