Good evening everyone hope all is well. Question: Dude at work recently purchased a garage kept 2018 Jeep Grand Cherokee SRT8 with 10K miles on it he mentioned at some point next month he would do an exhaust modification and have it tuned by a professional and was wondering if it would be safe to do so?

You will likely void your powertrain warranty's final few months if you proceed. Idk why someone needs to mod exhaust, I have a 2017 V6 Mustang and it's cool when you go 0-60 really quick, then it's annoying after a while, and I modded my exhaust. The stock ones were already quite a bit louder than my wife's 2017 EcoBoost.
True
I’m ambivalent on this one. The 6.4 hemi is a pretty good motor, other than being thirsty. And it is intended for fairly heavy loads (I believe it’s the same basic motor as in the 2500 Power Wagon). Tuning it for increased torque at low RPM should be tolerated OK. But I wouldn’t load it high in the rev range.
Also, keep in mind that a 5-6 year old hemi is vulnerable to problems regardless, especially lifter issues. Not necessarily fatal, but any performance tune will likely only accelerate wear .
Alright. What about the Pentastar V6? I own a Grand Cherokee with that engine and thought about possibly having a tune done only if it's not to be problematic
The newer pentastar 6’s are ok engines, but I don’t think they typically see a lot of mods and tuning. They’re not performance engines, so there’s probably not much to be gained from a tune. (I’d just do maintenance stuff: replace the air cleaner and plugs, clean the throttle body, that kind of stuff.)
A piston I have came from a 2010 Dodge Journey with that engine, I got it at a junkyard a few years ago, lol. I anodized it, put electroless nickel on it, and did the piston rings in copper, lol.
Neat
