What muffler to replace stock?

[jimmy j]

Just wondering what muffler to use to replace the OEM muffler. I'm not looking for any performance gains (truck is pretty much stock), although any would be great, and I certainly don't want to lose any performance. Just want the AVY to have a l'il more grunt. Any suggestions would be great.

What are the inlet/outlet sizes for the OEM muffler?

Thanx.

You could also search "Flowmaster", that will also bring up a lot of muffler debates.
