I did a resonator delete but before that I changed my stock muffler to dual aFe's. After the resonator delete it was louder but not so loud it bothers the neighbors, I got pops and burbles too, I love it. There is some drone but I grew up in the 70's in the American muscle car era so it doesn't bother me at all, I like it.
