I just had my new ebay muffler installed and I must say, everyone who said they suck are dead wrong. I love this muffler. It has a good deep tone but it's not that loud, but still louder then stock. it's a straight through design with a perferated core, no louves. So once again, E-BAY ROCKS!!! and for under $40 shipped to your door, what more could you want? I would recomend this to anyone looking for a new muffler.
