New TRX owner

Picked up a 2021 TRX over the weekend and drove it 13 hrs home from Nashville. Incredibly comfortable ride. First TRX, second HEMI. Love this truck. Noticed some squeaking/squealing at idle, though. Buddy of mine who owned a Hellcat Charger and a Trackhawk said the noise isn't normal and could be the blower snout. It's quieter after the engine warms up, though.

Check your pulleys. If it has an incognito/predator or other slip on lower that could also be the noise.

Also search for the cat tick which is prevalent on the TRX, it is simply due to the exhaust gasses and ground clearance causing it to be louder.
My bet is the cat tick though.

If it goes away when warmed up, it's most likely the exhaust crickets.

The squealing at idle is very common on the hellcat motor in the TRX. Its the pulley and belt. 100% normal. The 27's even do it.
