Anyone instaled the Corsa system on their 05 GT? If so please let me know what you think.

Here is a link to their sound clips

That corsa exhaust sounds pretty nice

 

but man it costs alot

 

i realize that ford did a darn good job making the exhaust system for the 2005 mustang GT but is every one saying that there will be no HP and TQ gains with an after market system. why dose corsa advertise 13 HP and 9lbs of TQ. i realize that it is not much of a gain an every one is switching their exhaust to get more of a mustang sound. but is corsa pulling our leg? i didn't really like the sound that they make but i am switching for more power not sound really. i did like the sound of the borla they sounded mean but dose any one know if there is any gain with the borla system? any one have one on there 2005 stang yet?
