Add a sound-amplifying exhaust tip. Exhaust tips with dual walls, flared ends or large diameters may increase the sound volume of the exhaust output. Increase the size of your exhaust pipes by 1/2-inch to 1-inch in diameter.
Piping is 2.5in inlet from the cat to two 2.25in outlets. It has a nice deep throaty sound, pretty loud if I'm driving hard but fairly quiet under 3k rpm and it doesn't drone. Good mid-range torque response. Just some comments on a few of the exhaust that you mentioned from what I've seen on my friends cars though. The HKS hipower resonator hangs kinda low, apexi dual N1 looks nice and pretty quiet, BC spec2 is deafeningly loud...love it.
