Necessity of a CBE for a stage 2+ tune
I will be making the switch from stage 1+ to stage 2+ as soon as I get my ar design DPs 
But as of now I do not have a cat back exhaust system. I decided to go the cheaper route and just had my muffler deleted.
I realize the benefit of having a CBE but I have heard that the stock system isnt that restrictive to begin with.
Would it be safe to move to stage 2 w/o a cat back? If so, how much will a CBE help with performance once I have switched to stage 2+?
Thanks
