2023 Jeep GC Overland L. Got the tech package with massaging seats...very nice. It's my wife's vehicle, but definitely the go-to for hauling the family around.
On my 21 GT perf pack 6MT, I get about 20mpg from mixed and 25mpg highway. I do not go easy on my car, but I don't beat either. I always put in top-tier 93 gas.
I've got a decent stereo that I'm pulling just under 2k watts rms...wanted a battery upgrade over OEM when the time came. I know it clicks everything on from time to time so for sure getting extra draw compared to stock. It's a 21, so about 4 years is fair imo.
Gotcha...I know Roush makes a similar setup for their cars. I prefer the OEM active exhaust due to quiet mode time settings. What you may want to do is a ghost cam tune. That will give you all kinds of burbles. It can be set to disengage at a certain RPM and go to a map for normal driving.
...you need active exhaust. The "valves" you're referring too are the muffler valves that can go from fully closed (quiet) to fully open (loud). If you want those sounds, which I also love, you'll need to do an H or X pipe that replaces the OEM resonator. Also, doesn't matter if the car is...
H-pipe on my 21GT and LOVE it! I have active exhaust so I can choose how loud I want it. The 5.0 is still raspy at high RPM, even with an H-pipe...just the nature of the engine. But what I like is low RPM in track mode. Lots of grumbles.
