Putting on the boxster s exhaust did nothing for sound or hp. It is exactly the same as the base muffler with a different tip. The reason the "S" has a deeper sound has nothing to do with the muffler, but rather the larger displacement of the engine. People "gut" the muffler to get a louder sound. This basically means they cut it open and cut some pipes/baffles to allow a louder sound although it does not offer more hp.
