T-Trim + V2 SQ Hybrid
After talking with Vortech it seems a T-Trim Volute/Impeller combined with a V2 SQ gear drive is available as a custom option. If you want a quiet blower for stealth without the loud V1 gears that normally come with the T-Trim, just ask for a custom head unit.
Found this out while talking to a tech who noted I can upgrade my S-Trim to a T-Trim involving just a swap of the Volute and Impeller, keeping my existing super quiet gears.
The V1 gears are noisy but have heavier duty bearings. These bearings are required for direct cog setups like most Mustangs run. If you are doing an LS1 direct cog Vortech, it's a bad idea. But I think most LS1's are running serpentine drives or serp to secondary cogs which are fine with V2 SQ's.

Will probably wait until next time car is down for major repair. Also need to see how these R1 Slicks hook up 600rwhp on the street. The Vipers have been having great luck up to 700rwhp. I run the same tire sizes.
But if you want quiet, just request V2 SQ gears and it's assured.
