Stillen exhaust or straight pipe?

onefastz

I currently have the Stillen exhaust on my car now. Before I had it completely put on, I cranked the car without the muffler and loved the sound, but couldn't justify spending that much money on an exhaust and not put the muffler on too. So, what are the pros and cons of getting rid of the muffler and straight piping over the Stillen? (I plan on removing the Stillen exhaust and using the stock exhaust for the straight piping). Power loss/gain? Sound? (I know straight pipe will be louder, but is the sound that much better?) Any thoughts and information would be greatly appreciated!
