what is the best bang/4/buck on mufflers for a stout 340?

I went with Magnaflows,not by choice. They sound ok when your just driving normal,but when you hit it the sound changes dramatically,I don't care for it.Only had em 3 months,so I will live with them for a while longer,maybe put in a "h" pipe. 8)
