So far, this is exhaust has been on my car for two weeks. The exhaust is definitely best bang for the buck, since it provides a really good sound and Andrew at AA has confirmed that there is a power gain from stock. Also, the exhaust is 18lbs lighter than stock. I also want to point out that this exhaust does increase mpg, so all the other owners out there see if it's the same for you, 23.7mpg --->> 25.4mpg. Not to mention that I have been flooring it at lights and in the deck to hear the exhaust
, so it probably gives even more than that. The only down fall is the drone around 2-2.5k rpm. Other than that, this is probably the best option if you don't want to drop 1k on the exhaust.
Medium Loud Exhaust

Here's a quick comparison from stock:
