I am actually going to be welding up a complete custom exhaust next Saturday. Going to be using the mufflers from MRTs Camaro SS/Mustang Interceptor system as heard here:

I had a magnaflow 2 in 2 out with the built in xpipe put on my car. Really quieted down the idle, starting about 3k it sounds exotic.

"It's a well know fact that after you hit 400 HP you have to go with split dual exhaust like the LS2 GTOs. The '04s could get away
with single side because they were only 350 HP. With 400 HP and beyond the car wants to turn right at WOT from the thrust."
They did have the heads up comparison somewhere but can't locate the link. What I DO have is the youtube video of the comparison. Again for what that's worth to you. I feel like various engines, head/cam/intake combinations require different exhaust setups/flow.
I think the smallest they make is an 18" overall length. For the price its not awful. Its got an internal X as well so you MIGHT be able to use this in place of a traditional X pipe. X pipe, muffler/resonator all in one.
After some quick measuring my SLP X pipe is about 22" long from the flanges back so it may work in place of the X.
The MRT mufflers(which looks A LOT like the Vibrant quiet resonator) are 14 overall length with the body 9 3/4" long. Those should tuck up just fine.
I will say the stock 04 mufflers are possibly the smallest stock mufflers on any car I have ever seen. They are about 10" long and 3" deep and like 8" wide I think. Really small.
Last I remember you should factor a muffler flow requirement of 2.2 CFM per HP you make. 350hp car needs a 770CFM (or more) capable muffler if using one, or two mufflers capable of flowing 385CFM (or more) each.
This is if you care about building an exhaust to benefit power rather than being a noise maker. There is a lot more that goes into building a beneficial exhaust like x or h placement pipe size etc. But if you just want sound then all you need to worry about is space available. If you want performance, google "zero loss exhaust systems".
It's most likely not the width and length that is the issue, its the height for ground/driveshaft clearance.
Definitely not building for sound. That's easy. I am modifying my SLP X pipe(that I repaired for a guy about 4 years ago and never picked it up) to sit up about 18" away from the collectors ala Svedes measurements. I am going with two rather quiet mufflers from MRT that should flow very well but not generate a lot of noise. Noise is not power...For a reference I picked up my goat in the middle of December 2012 with about 50K on it. Since then I have put on about 11K miles on it. This includes a 6 week work trip welding in Bermuda where NO ONE drove the car and 9 days of the car being in the body shop fixing where some clown backed into me at a stop light. So I drive way to much to deal with lots of noise and certainly can't stomach FM levels of drone.
Trying to build everything with performance in mind. Function over form so to speak.
