What is the difference/benefit between 1-3/4" and 1-7/8" Super Pro catted system? I have a base 2013 LS3 C6 with Corsa CAI and Borla S-Type II axle back exhaust. Is there a specific pipe to maximize results on my existing setup?

You should go with the 1-3/4 for the best results.
Having said that, many people put 1-7/8 on non-FI card anyways

I don't think I lost any bottom end torque with the 1 7/8" LG Super Pros. 2011 GS is totally stock with NPP exhaust and MN6 transmission.
Do you install them for free too? Another forum vendor out here does, they put mine on and did an excellent job. Took less than 3 hours for them to do it.
in terms of "losing torque"...back when I had just my PFADT headers on that exact same dyno you went on I hit 445rwtq with just the headers and the HP tuners tune on the NPP muffler. Just a little FYI.
EDIT: Here's the old dyno sheet. Just a tad more torque PFADT FTW

FYI - The average dyno has an error rate of 1-3%. On any given day
it can be off +/- those number depending on how many runs the dyno
has done, how many runs the car has done, atmospheric conditions
and a whole host of other factors.
Having said that:
LS1's are more prone than LS2's, which are more prone than LS3's.
This is a historic argument among Tuners, about half will say you loose
it, the other half will say it is not an issue.

Just saying both cars hit similar RWHP (423 vs 427) but considerable torque differences demonstrating the size of the piping differences in "low end torque"

Hey Nosferatu, are you 1 3/4" ? I was thinking you were also 1 7/8", even though you had the PFADTs (versus the LGs I have)
No question, 50 lb-ft at 3k rpms difference is impressive!!
And for others reading, we both had our headers installed and tuned by the same shops, and used the same dyno. He was earlier in the year, and when they quit selling PFADT headers for a while, I went with the LG super Pros.
I'm still planning on doing the supercharger setup you have too!! It'll be interesting to compare, because I plan on doing the same setup you have. We can then compare again, because the headers should be the only difference.

I get it, would love to sell everyone 1-7/8" just want everyone to understand that they could get either/or results...

Yup 1.75". I bought them planning on NOT going the route I did (forced induction) Either way, they still make plenty power.
