Need to have a muffler put on my Saturn was wondering how much it would cost me to have that done

Walt's will give you a estimate. Just ask them how much will it be.

Regular muffler around $50. More if you need aditional exhaust work or something performance based.

Reasonable prices there..i got part put on muffler..for 50

Without all the details its hard to guess, nut I had a Saturn that needed exhaust work a few years ago and it was in the 150 range, much cheaper than of you go to Mineke or Midas pot one of the big shops.
