Turbo cam question

Well if I thought I could get away with it or if I had a strip only car but this is a street car so it needs to pass inspection so muffler is a must. I have a cherry bomb 2 muffler on it but its not a straight though muffler and I'm guessing will have the same back pressure problems as the flowmaster. I've heard some people run the race bullet mufflers. It is a straight through design.
