This is basically the kit we ordered.

The cost from perf shop was under $500.00, I want to say slightly over $450.00 in parts, then up to 3 hours of labor, as they have not done TRX yet. But its every option you can get. Same set up I have on 2019 Laramie sport, but single cutout version and its loud, I can’t imagine how loud it’s going to with 2 cut outs. Only a full throttle, accelerating video will do it justice and a decibel meter.
The Y pipe allows you to attach the 11300 Adjustable Turndowns, so you can redirect where you want the exhaust to go. You wouldn't think it would make that much difference, but if its pointed to side and rear of truck, it allows exhaust to resonate out at other cars and out the rear more, its louder on both the side and rear, than if you just point it straight down at pavement, like in the red TRX video.

With the video of the red TRX, the cut outs are facing the ground.

QTP sells a 3" Y Pipe that you weld in, so exhaust is not dumping into the pavement, it pushed to the side and the rear. It’s extremely loud. Its like having side pipes and rear exit.
This is the way to go if you want a really loud truck when out on road messing around, handing out ear crackers to the wannabe's. Believe me it gets old pretty quick leaving the exhaust cutouts open all the time. Just hit the switch/FOB and your back to pretty quiet stock exhaust.
I had my set-on Laramie since January 2019 and have not had one issue and I live right on the ocean, where salt air and marine salt sprays up into air from waves crashing into the beach and that salt air corrodes everything, left outside. Its hell house exteriors and car rotors.
