The mufflers tend to be quieter but it should be understood that in a stock E body, the system was designed to work together (muffler and resonator), if you remove the resonator, it definitely gets louder, however you will get some reverberation through the trunk, however if you remove the mufflers, it will get louder (throatier) but you tend not to have that reverberation in the trunk, at least this has been my experience. On my Cuda, I have Magnaflow mufflers in the stock location and it sounds good, but on my Challenger I only have the resonators and I think it sounds very good.
