I have a 95 3.0 4runner. my muffler is rusting out and needs to be replaced. i have never done exhaust work my self but i would like to. what muffler should i get. performance is nice, but i have to make cost a priority. something decent that i can install w/o welding. also, my cat doesn't seem to be leaking, but is the same age as muffler so will likely need to be replaced at some point too. thanks for any help.
