Invidia Catless Downpipe and a protune 2015+

Hey guys,

I've got the invidia catless DP coming and will be protuning it. My car is otherwise completely stock. Anybody else done this? What kind of numbers are you getting? I don't wanna get too crazy into modding my car. Did alot of research and found that a DP upgrade and a tune is the best bang for the buck.

What do you guys think?
