The exhaust is an MRT Interceptor. If you haven't heard it, holy ****! It is one of the deepest, best sounding axle-backs I have ever heard. Very low tone on startup, very beefy sound through the RPM band, but almost silent in 5th and 6th gear on the highway. I heard it in another 2013 GT then bought it on the spot.
When I do the cold air intake, I'm doing the JLT Big Air with the Bama Tuner from American Muscle. I'll also add the 3:73 rear differential at that point, but I'm going to wait for a bit to figure out which local dealers will be more lenient on factory parts/ warranty issues.
I got Sterling Gray, and will add some Azure Blue Metallic accent stripes next week when I get the other work done.
I'll definitely post pics when I get the car back in a week or so.
