There is obviously not enough discussion of mufflers on this site and Britt could surely use another thread on this.

Can someone please detail the installation of those newfangled muffler needle bearings and/or the roller muffler and list the benefits of each.

And, just so it's not OT, which muffler is best for making a completely bone-stock smogged 1.8 feel (and sound) like a ferrari while on jackstands?
