I bought the SPT catback and installed it today (with 750 miles on the car at the moment) and took the car for a test drive with my younger brother. On the way home I was waiting to make a left turn, and in the other turn lane (it's a 2 lane left turn) 2 guys were in a Taurus reving at me. The light turned green and I made my turn normally through 1st and the beginning of 2nd, then pushed 2nd up to about 4250-4500 rpm, then went to 3rd and did the same, then shut down, with the Taurus about a bus length back. They stayed there for about a block and turned off. Although not a very impressive kill, it was still fun. Oh, and the new exaust sounds great!
