The Raptor turbo muffler from Kragen's sounds pretty good for its price($24). I run one on my 3.0 and it has a nice mellow yet throaty sound when on the gas, I haven't put one on my '91 so I am not sure what it sounds like on a 22re. The muffler isn't made from the thickest guage steel and wont last as long as a high $$$ muffler, but then again they are cheap enough you can replace them whenever it is needed.

More than tread lightly. Leave it like you were never there, nor anyone else.
