95 4runner
 

what kind of muffler should i get to help get a nice deep medium loud roar? I couldnt find any flowmasters.

Wow, really. I have a 40 series dual exit flowmaser on my 95 pickup 3.0 and it sounds great, but for what you are looking for I would recommend the 50 series. Now this is not a kit sold by flowmaster but a local exhaust shop should be able to do the install for you.
