Ok I just read my last post again, I'm not sure if I was clear. My question, is anyone running the top speed or similar mufflers on a 98 model year Boxster. Because on this year the car only has one set of cats. So I wouldn't think I need the test pipes to get rid of the drone caused by the second set of cats on later model year cars. The set up on this model year is header, cat, pipe and muffler. Thanks in advance
