small exhaust shop dude, I have had friends that worked for midas and man have I heard some stories. I paid $20 to have my resonator removed. Had a glasspack put in for $30 at a later time. ($15 for the gp, $15 for labor) Had the rear muffler removed and a straight chrome pipe put in its place for $27, including the price of the chrome.... stay away from the big guys, find ya a good, small exhasut shop and just go in and chit chat with the guy for a while, tell him what you are wnating to do, for the sake of conversationa ask what he would suggest (which from my experience is usually flowmaster) and then tell him what you really want and save some big $$
