I have the same mods, and its not loud for me, and I don't have NPP. My car doesn't rattle when the rpm's come down on a start.

Edit* The issue will be finding someone with a older version of HPT. 4.1.6 was the last version before this feature was removed and it only works on 2021 and older vehicles. 2022+ require a newer software version to read and edit, so these cars will be stuck with the obnoxiously loud start-up due to the "cat-warmup" feature being locked to enable.

Hey carlythecamaro- King provided you the fix above... I spoke to my tuner about this as well, and he liked that sound (me... not so much) Just like King stated, it can be tuned out.

Thank you for the reply, I will speak to the guy who tuned my car and see if he will do this for me. The sound is driving me nuts!

Who did your initial install and tune? Assume a speed shop/tuner? They will have access to HP Tuner and both the older version and new versions. Some tuners carry a laptop for the older version, and a separate laptop for the newer version/update for obvious reasons.

Contact him and see if he will disable "catalyst warmup" for you. If not, I can. I am in the Fort Wayne area. But it would be cheaper for him to do it because I would have to license your car to my MPVI in order to flash it with an updated tune.
