forget the cut outs. If you want noise get the X pipe or pro chamber. I removed my X pipe cause it was to loud with the top down. I removed all of my cats on the stock pipe and it is a happy medium.
You can do the install with hand tools and ramps. The rear connection is a breeze. The front passanger O2 sensor is a ***** to get back in and watch the gaskets to the manifolds ( use a little gasket sealer to hold them in place. If you are even mildly mechanicaly inclined you can do it in a few hours
