I just got a flowmaster super 44 and 2.5in mandrel pipe. its not loud but sounds aggressive from what i understand this is what you want. its not over powering but sounds mean at the same time. Its a low grumble not farty at all. go to http://performance-curve.com/84-01ch...ailpipe-1.aspx. its very cheap and good quality and pretty much comes with what you need. youll like it trust me. you wont regret it.
