Would that make a difference? The setup like the HKS is very intriguing but may cause a headache for the muffler shop? Interesting, nonetheless!

if you just add another set of resonators it will just deepen the tone. The above HKS setup is Heimholtz chambers. The key is running them like 90 deg off the pipe. You don't even need the full bottle type resonator, a length of 2.5" pipe welded off the side and capped on the end will work just as well.
