Headers just seem like a nightmare for me in terms of finding a reputable place i could trust for such a difficult looking install. I am already worried about trusting a shop to install HFC/TP's.
Again, i super appreciate all the advice so far guys!

On a 300hp+ car, the +/-5hp difference you'll see between TP's and HFC's will be hard to notice anywhere else than a dyno. Any butt dyno gains you feel will be psychosomatic.
With a regular cleaning schedule (as any sports car owner should already have), your rear bumper will not suffer any increase in dirtiness from TP's over HFC's. Especially due to the fact the FI tips stick out ever so slightly past the rear bumper. Also, a good wipe down with Mothers Mag & Aluminum polish will keep the tips themselves clean. If your engine is producing
that much carbon, you should take it somewhere and have the tune looked at.
As for the header install, it is not for the faint of heart, but it is (and has been) done DIY, so it's not impossible. A TP/HFC install is easier to do in your driveway, provided lifting ability and the right amount of extensions.
