I also run the MAC flowpath on my 97 GT. I think its the best sounding exhaust, I love the way it snaps and pops on decel. IMO flows only sound good on a pushrod motor. If you have to choose between Magnaflows and Flows go with the Magnaflow. I ran a Magnaflow catback and a UPR o/r X pipe on my 01 Cobra and got compliments on it all the time.
