So going TBE on my 07 STi... and some other goodies

So...I still have my TBE from my 03 WRX and was wondering if I can swap it over onto my STi and if it is safe. I'm not THAT familiar with engine response on the 2.5, but I heard that going fully catless TBE can create engine knocking without a tune.

I currently have a Helix DP and Skunk2 CBE, will I have any fitment issues? And is it safe to be catless without a tune?

I also have a perrin adjustable rear sway bar I think it was 22mm, I'm not sure, but will that transfer over no problem also? DO the 03 endlinks fit on the 07 sti?

The swaybar & endlinks are different on the WRX vs STi.
