'04 Muffler size needed

[Thundermouse]

I must admit that I don't know much about the v6 models, so I ask for yalls expertise.

A friend of mine has just bought an '04 v6 and wants a new muffler that sounds noticeable but isn't trying to be so loud that it sounds like a fart can on some ricer mobile. I'm recommending to her the Flowmaster Super 40 but I have no idea what size she needs; do the '04 v6s run 2.25"s, or 2.5"s. I'm guessing that it's 2.5", but I want to make sure before I order it for her.

Also, will welding be required, or will Flowmaster send me some clamps.

Thanks

2" or 2.25" with welding require
