Best Catback Exhaust for 2011 Ford Mustang 5.0?
I've been doing some searching but the majority of websites never even mention actual performance gains. Most of the time they only talk about how loud the exhaust is. Does anyone know where I can find actual dyno results for the various exhausts offered for the 2011 5.0?
(I'm also interested in any proven gains from any mods for the 5.0. I'm very familiar with companies that produce parts for imports but I'm completely lost when it comes to domestic modifications.)
Justin, I'm really more interested in power than sound. Sound is important since I don't want it too loud but power is more so.

EW, the stock exhaust system in your Mustang GT is fairly efficient form the factory. The same basic exhaust system with only minor differences is utilized on the 2007-2009 Shelby GT500 (in the case of the latter the H-pipe is swapped out for an X-pipe and mufflers tuned for an automatic trans equipped Mustang are utilized). The stock exhaust uses mandrel bent 2.5" stainless tubing for a consistent cross-section throughout. Muffler selection at relatively stock power levels is more a matter of sound than power and will net a very little (if at all) increase in power by swapping them out.
