This may sound like a weird question, but are you looking for a better sound for yourself, or outside the car? I ask because all performance aside, so much of what you hear inside the cabin isn't the exhaust at all, but the intake tract noise. Just remember: If you want them to enjoy the sound of your car, work on your exhaust, if you want to enjoy the sound of your car, concentrate on your intake tract, (adding a cylinder makes a Volvo motor sing)
This exhaust...3" end-to-end with 1 race cat, 1 16 inch glasspack (I was totally amazed that this was still working 10 years after it was installed), and 1 straight through Magnaflow followed by a reproduction of the factory "S" bend to help control in-cabin resonance in a wagon.
Outside, my car sounds nifty enough, kinda like a Group B Audi that's gone through puberty and learned some table manners...

Inside, however, you can hear Eric's beautiful header get after the job and make all 4 inches of intake work!
