This muffler performs and sounds like an OEM. Very quiet and easy to install on my NEON. Love the fact that it came with hangers in the right place. I love the fact that the exit curve is perfect. I had to cut a small notch in the intake pipe to match the knob on the stock exhaust pipe. This knob prevents the muffler from rotating. The intake side matches the existing exhaust pipe perfectly, but I couldn't use the original muffler clamp so I decided to buy another one. It took me an hour to install in my garage. Very satisfied and would recommend!
