I went with the 3" stainless, X pipe and mufflers all from Magnaflow. It fits and no rattles but it is tight in places. I also installed four stainless mufflers and it is still pretty loud. I also installed two turbo style stainless clamps on the pipes where the turn up to go over the differential. These clamps are reuseable and easy to remove. Remove the clamps and the tailpipes and rear mufflers come out. Unbolt the header collectors and the entire exhaust system is out in less than ten minutes.

Here's a few pictures.
