well the rule of thumb is, you get what you pay for. If all you really care about is just getting a noticable exhaust sound then yeah I'm sure a flowmaster would get the job done. I couple of my friends have the bolton stainless steel exhaust from Ractive, their around 200 bucks, they bolt right on, sound pretty good, doubt they give much if any performance gains but that'd probably be the way to go if you want something pretty good for your buck. Just my two cents.
