Ive got a muffler delete on my car. Straight pipes from rear axle back. I kept the stock tips and them welded on. OEM headers and both cats. I'm pleased with the way it sounds. As far as droning, if you listen to music then it really isn't as big of an issue as people make it out to be.
The shop I had it done at only charged $80 and since its a 325 and wont go fast anyways, I wasnt going to drop money on a full catback or even performance muffler.
