Seeing a 100HP gain from "int/exh" only, would be "ambitious."
A 100HP gain from
Intake/Exhaust
AFR mods
Spark curve mods
Some other stuff I won't go into (yet.)
Is still a tall order.
This isn't because the mods are "that good" but that the OEM equipment isn't "that bad."

Zero chance of making 100hp more.
You would need a high compression engine (c8 is already high compression) heads, cam, I/HE and some alternative fuel because 93 Octane won’t get you there , and finally the ability to tune the car.
Some type of port injection will be needed as well.

100 extra hp. Agreed, not happening.
GM will give the access to a few, but have not yet.

Are you saying that WHP before is approximately 450. And the WHP after is approximately 550. That would mean in 1/4 mile instead of
10.9 seconds it would possibly be 10.5 . And 0-60 3.5 seconds.

Probably $6K for that "package" (intake/exhaust) 
. Sure hope Taadge contacts Mr. Lingenfelter soon! Missing out on 105HP from a few simple mods and stickers.

I live in the Little Elm area but this is not far from where I work in Lewisville. On my next if office day I will have to do a drive by and check it out. I will get an update but it could be Tuesday next week.

600 at the crank (with 93 gas) won't be possible without a cam swap. I would guess that with a stock cam, e85 tune, and a compression bump to 12:1 would still only put you in the 580 range (along with the mods listed). As for injectors, I've made 705 crank in the LT1 motor which is about maxed out. I added the LT4 low side for insurance afterwards because I was on the edge.
