My final update for now (I think) is that I've finally decided to venture from the stock catback. For the past year, I've had catless downpipes and the stock catback and while I do like the sound, I want a little more agressive tone without being raspy or obnoxious.
Last week, I ordered a Magnaflow resonated X-Pipe and some 2.5" and 2.25" flanges. My plan is to continue 2.5" flanged piping from the downpipe connection into the X-Pipe, out of the X-Pipe, and then neck back down to 2.25" for the "Axle back" connection. At this point I may or may not add a flanged connection like
@SM105K, jury is still out even though I went ahead and bought the flanges and gaskets.
Also, since I first bought this car I have always thought it should have come with Quads. If the GT500 can come with quads why couldn't the SHO? Haha. I decided to buy a cheapish set off eBay to test with, since I want to keep stock mufflers the main concern was the point at which the bumper starts to brake over and didn't want it sticking out.
First set purchased:

However, my fear was confirmed, as these would stick out about 1" past the brake over point. After doing more searching, making calls, and taking measurements, I found these:

The angle of the tips matches the SHO bumper almost perfectly, and by mounting this in the stock tip location I'll be moving INWARD instead of OUTWARD which will accomplish my needs. I realize the second tip will likely do nothing, but at least it will look cool haha.
