So about a year ago I went to a shop to have my exhaust done. I had the guy remove the muffler, and just go with straight pipes. It was great because I got the sound I wanted, and there seemed to be very little drone. Only now I realize that there is drone, and a lot of it, when sitting in the passenger seat. Right under the passenger seat is one of two small resonators/mufflers still on the car.

Would upgrading to a performance resonator or a glass pack help to alleviate some of this drone? Are there other options I haven't considered (other than putting the old muffler back on)? Money's tight, so I'm not looking for an entire exhaust rebuild either.

Thanks!
