I have tried running my car with the muffler disconnected. It's louder than hell and sounds like crap. With my aftermarket straight through muffler, it's just the right loudness and sounds great

The Boxster's exhaust piping is an oddball size so you can't actually fit any stock size CC inserts in there. I think it's somewhere between 1.75" and 2". I tried 2" CC inserts and they wouldn't fit.
