"Installing it wasn't too bad, the instructions could use better pictures, but the problem was the clamps. It took forever to get the clamps in just the right spot - even with the right torque on the bolt - to not leak exhaust at the clamp. One of them still leaks a little, so I'm going to fix it with some muffler cement. Other than that issue, the exhaust sounds orgasmic to my ears, I love it. "
