I ordered mine with the new car build and it's installed at the port, not at the dealership. To be frank, what little I've been able to hear (and see) on YouTube, the Dinan does not impress me. I only have approximately 100 miles on my car and the M Performance exhaust produces powerful and deep throaty burbling sounds. Like the Dinan on YouTube, I have yet to hear any uploaded sound clip that captures what I'm getting from my exhaust. The Armytrix sounds similar to the M but it's almost $3k before installation.

I was able to get the M Performance exhaust for $650 shipped. Doing the install on my lift at home and taking my time I did the install in about an hour with minimal tools or effort. Since its only an axle back I just measured how long the pipe coming out of the new muffler was, marked that distance on the stock exhaust piping, and cut it with a sawzall. Then I just unhooked the valve, unbolted the hangars, and swapped them and the tips (tips were quite a bitch to get on and off reusing the stock ones but is doable) back on with the included clamp and I was done. Having the lift made it easier, but if you can get the rear on some ramps or jack stands, it would be more than enough work to get to everything you need access to.
