Can I run a full exhaust without a tune
 

Just got my Borla uel headers, invidia downpipe resonated and a Perrin overpipe
I already have a Injen intake and a GodSnow catback installed but I have no idea if I can Install my other parts without getting a tune? I'm gonna be getting a tune soon once I find out wher I can go but I'm not sure if I can install the parts now?

Yes but you might throw a CEL due to the catless header

The engine will be fine tho ? I'll have a tune within two weeks

Just don't go WOT and take it easy. You should be fine.

I have Borla Version 2 UEL catless headers, Invidia OP, Catless Invidia FP, Invidia N1 Titanium tip Catback. Just installed it last night. Have driven about 100 miles, did some WOT pulls as well.....No CEL, no hiccups.

You've already installed the Injen intake and you haven't gotten any kind of tuning done? Using an aftermarket intake without a tune is a much bigger deal than using aftermarket exhaust parts without a tune.
