I don't mind the drone and my rasp goes away after the car warms up. but heard it is worse on an svt- i have an se. that is why I say take it to the muffler shop- they do dozens of custom jobs and can fix ya up so you have no drone and no rasp-I know people have done their exhaust and have no drone or rasp. there are mixed opinions. i know down here in Texas I have been told the res counts as a muffler- so your rear mufflers can be removed without worry of failing inspection. I would do a search in pics and vids and on exhaust and listen to what the differences are- then go with what you want to.
