Maybe I'm biased, but I installed it on a 2005 Jeep GC with Hemi. I don't have a resonator, just a straight pipe into the exhaust pipe at the outlet. It's really not that loud but has a nice deep tone. I personally don't think he has a drone. I'm happy with that. Any modified Mustang or Camaro is way louder than this one. I expected the exhaust to be noisy because it's a "glass package" and literally just a straight pipe with some baffles, but it really isn't. Actually my MPG has improved so I assume it creates some back pressure because the exhaust is 101, you can't have a totally free exhaust, you have to have some back pressure. Regardless, I'm happy with it, but don't expect it to crash depending on your setup. Window.
