The current system on my car has seen better days and its time for something else. Ive had Flowmasters on every Mustang Ive ever owned and like the sound, but want something else. Going with either MAC or Pypes Ciolator catback. Havent heard either in person and cant find good sound clips of the Pypes mufflers. Is anyone using these, and how do you like them? Just wondering if the MAC system is worth the extra $100 or so. Pypes is local to me and I can pick one up for $240 complete. Currently have stock headers and catted h pipe, but will be going with some shorties and off-raod H pipe. Any opinions appreciated.
