Looking to do some work on my 05 cts but don't know where to start. Want to give her a make over seeing as she just hit 100k...still performing excellently except for a power differential bushing issue any advice?

The rear differential bushing was a little tricky but hopefully my thread I started and posted my experience will help you. Last few posts on this thread have my diy.

It depends what you want to focus on first. I am a huge proponent of form follows function. I, personally, think that performance trumps appearance, and thusly, would start under the hood.
The aftermarket for the LY7 is quite limited, but what is out there seems to work. Cold air intakes, from various manufacturers, are available. Volant is pretty popular around here, as there have been independent dyno tests to show its results. I have one and am quite happy with it.
RX Performance has built a host of accessories for this engine, including an intake manifold spacer, breather cap, and catch can. All of which seem to come highly recommended (I have have all of them, just waiting to install).
External transmission coolers are also a recommended upgrade. Just a word of advice, get one with 1/2" input/output, to match the OEM lines.
Between RevShift and Creative Steel, you should be able to find all the bushings and mounts you could possibly need.
Grabbing the stiffer springs, stiffer sways, and a larger exhaust from a CTS-V gives you factory fitting parts built for a heavier/sportier car... these are all very popular upgrades.
BMR Suspension makes some heavy duty suspension components meant for the CTS-V that will fit.
Other than that, if you are wanting to change the appearance of your car, look into grabbing both the bumper covers and side skirts off a Vee-car, debadge, and keep her clean.
