I don't want to spend hundreds of dollars on a new exhaust system, but would like a meaner sound from the car without the drone. I've read all the posts and it seems that the Brylcreem mod has less drone than going with straight pipes and reso delete (or reso delete and BB kits). But, I am concerned about the rattling I've been hearing about if you do the Brylcreem mod. Anyone want to chime in with an opinion? I have an 07 R/T (but not with the R/T package. It sounds like from what I have been reading, that my suitcase is not free flowing like the R/T package Chargers...is that right? If so, sounds like the Brylcreem is the way to go...just have to watch for this rattle problem. Anyone know where the rattle comes from? Is it just the muffler shop not doing a good job of securing the pipes?
