Start with an intake, have some fun listening to the SC whine, then decide if all the other stuff is really necessary. There isn't a big need to play with your exhaust. You should really go for the SC pulley/tune combo if you want to unleash the beast inside!!! I went to the track last night and ran 12.85, 12.86, 12.90, 12.91 between 109 & 110 MPH with just a SCAI. The DCAI gives you a little more flow, low end grunt, and symmetry when you pop your hood(you know you can raise to 90 degrees, right?). Had a great time when the gf asked when I would start bracket racing!!!! These cars are consistent in the 1/4 mile as long as you are too. Have fun with your new ride and welcome to our obsessed community. You have 1 of 2016 coupes made(less now after wrecks and fires), so treat it right. Glad you switched from rice to sauerkraut!!!!
