I also had some leftover commercial carpet, so I did one layer of that to fit. (I have no spare or anything in my trunk). With the trunk mat in place, it looks 100% stock. Plus I can remove it in 30 seconds if needed.

It made a HUGE difference. The car is still loud as hell, but it's the RIGHT kind of noise. It actually makes the engine and exhaust sound 100% clear without all the tire and road noise. And when the weather is nice, I have the windows down anyway so I can hear the exhaust note even more. But it's nice to have the option of carrying on a conversation or listening to music if I want to.

It's been one of the best mods I've done to the car so far. Highly recommended. For $50 and about 1 hour of your time, you can't go wrong.
