Any reason you're set on that specific muffler? If I'm remembering right Pepboys sells the Flow 40's SI/DO mufflers for I think $80. Are you going to be running your own exhaust and dumping it? If so, here's a 3.0 with a Flowmaster 40 Series on it, if it'll sway your decision in any way or not. No engine upgrades or anything, just a CAI and this exhaust.
