I had a FlowMaster Delta 40 or Delta 50 muffler first, but it was just too loud inside. I just replaced it with a Dynomax Super Turbo muffler (see my post above) and I am very happy with it. It still has some bark to it, but it is much quieter inside.
The muffler was like $65 or $70 delivered, and I paid another $225 to have the pipes and the muffler installed.
Good luck!
