The crossflow Flowmaster just plain suck but what do you expect from a opposite side outlet Flowmaster.
As for my Mustang I used the stock H-Pipe and added only mufflers to the stock cat-back. I could tell a major difference in the higher rpms Flows vs Borlas. Given there is virtually no gain with any cat-back on a Mustang you could still feel the difference under heavy load and top end, if you can say a 99-04 GT had top end!
On my GTO I made a set of rear replacements for a buddy with a 04 with upgraded 05 bumper and exhaust. I used my car to set up the welds and tip placement. After I waas finished I figured I would see how they sounded. Versus the stock mufflers they sounded good but I could easily tell I lost some high end response if not some power too. The power and response came back the instant I bolted the stock mufflers back on.
