Well, I plan on ordering my exhaust really soon and would like you guys' opinion. I plan on going with a Steeda Catback, but for the midpipe I want your opinions. Do you think it would sound better to get the Bassani Catted X or the Mustang Tuning Xpipe? Also, when I get the O2 Sensor Extensions, do I just need one pair or more? Thanks for any input.
