Any information would greatly be appreciated.

The cats will yield 15whp. The OEM cats are very restrictive, so they make a huge difference. These cats are the same that we use on the earlier V6, just with different bends.

I'd really like to hear the LFX and not the LLT again since the engine exhaust is different.
The LFX cats and LLT cats sound the same. It is the same design and cat bodies, simply with different bends to accommodate the slightly different undercarriage of the LFX. Hopefully one of our testers can chime in and attest to that as well.
