I agree totally with your assessment on the wheel hop and quiet exhaust. The Ford Racing "KR" axle back exhaust is rumored to be a really nice sounding exhaust with no drone, I think you made a good choice!
I went with the magna flows because of a great deal from a friend, they are still too quiet but offer next to no drone! (I hate drone)
I'm considering the Ford Racing 3.73 gears as a "winter mod" but worried about a proper install.
I think I will address the suspension during this off season with the Track Pack
Maybe after the suspension I will open the hood, but I'm pretty happy with the power at this point.

I'm not sure that the handling pack will do anything for the wheel hop but it will help in the looks and handling dept. The gear install is pretty basic and no different than any other car. If you do it though there is a different inner pinion bearing required for the GT500 and a spacer that needs to be remove from behind the old one. Also if you aren't planning any performance mods a Ford dealer can change the gear setting to 3.73 for you as it was the factory ration on the KR. I used the gears as an excuse to get the programmer and since I was doing that got the air intake also. After hunting through all of the sound clips on the net the one I liked the best was the KR and I'm glad I made that choice. It's so hard to tell till you hear an exhaust system in person. It doesn't drone a bit and at highway cruise speed is actually very quiet.

I completely agree with the MagnaFlow assessment but they have gotten a tad louder in the last 3 years. I have 3500k's on my mufflers, how many on yours and has it gotten louder with usage???

I think they have gotten a little louder but very little I have aproxx 1000kms on them now.

I would like to replace them and do headers, anything to make it meatier sounding. My wife said go ahead but cringes and shakes her head. She thinks its plenty loud enough but what does she know tehehehe

Headers won't make it much louder, but an off road mid pipe will. Headers and an off road mid pipe = even better

^^^good to hear and thanks

Headers won't make it much louder, but they will make it sound a little more aggressive. The thin walled tubing resonates more than thicker walled tubing or cast manifolds. This will be more noticeable with full length headers. As for mufflers... If you want more sound with NO interior resonance (drone), the best mufflers on the market are Corsas. They are far from cheap, but are very well made, and will likely last the life of the car.

^^^ Never heard Corsas in person.

So the only mod that eliminated the wheel hop was the UCA? I have the same issue and was thinking of changing the UCA too as the first step, then maybe the LCAs next. Are you running stock tires, GY F1?
