The Vararam is my intake of choice when it comes to performance, so good call on that one. The exhaust is going to make the truck sound better, but you wont feel much of any power gain unless you replace the stock manifolds with a set of headers. Tuning is the big bolt on when it comes to power gains that you will feel, but it is not cheap on a 2016 model, and the warranty is always questionable when it comes to the dealership and your warranty. Many dealerships do not care that it is tuned where others will deny you if they find out it has a tuner.
