I have one and I LOVE IT!! I had one on my 2014 as well. My 2014 had over 160k miles when I traded it in and not one issue.
If your serious about getting one hit up Matt at Moe's Performance. He has great prices.
My 2014 was tuned but its great either way. My wifes R/T is not tuned. Currently my truck has a Veraram and a muffler swap and i think it has woke it up tremendously. Plus it sounds awesome and looks cool as hell.
Id say start with just a Veraram and then add as you desire. Matt at Moes has great prices and advice. He wont sale you something that wont help so ask him his opinion about adding the tb. He will steer you right, he is more about happy customers that return than making a quick sale. I have been buying from him since 2013.
