Have you considered finding a used Scatpack or Hellcat exhaust? They are the same design and might fit the bill. You'd just need to delete the AEVs.

I might consider that. How loud was your factory Hellcat setup? I can basically only improve from the cats back as the aftermarket AFE down pipes have been discontinued and supposedly didn't fit an AWD. Not sure why, pretty sure they are the exact same.
You're just going to get more noise than without the AEVs. They aren't that loud except under WOT. There are two styles of HC/SP exhaust. One has glass packs, and the other has case style mufflers. Both are straight through designs, and use the same resonators out back. 2.75" OD front to back.
The cat delete pipes got discontinued because of the EPA crack down. Your best bet is to get some stock mids and do the cat delete yourself.
I think the downpipes didn't sell and AFE did have an option with high flow cats. With cats, they were as much as the rest of the exhaust. I wonder if the larger 2.75" pipes would hurt low end torque? For a V6 this car is torquey and I want that. It goes from 2.5" to 2.25" with straight through glass pack mufflers and resonators. I have considered a better X pipe as the stock is a half *ss X pipe. Some aftermarket exhaust is 2.5", some is 2.25".
Since I tow, Dodge recommends both diffs at 80,000 km and the Transfer Case fluid at 95,000 km. I found another service job needed due to leakage. Changed the oil, 0W20 full synthetic and the transfer case fluid. The Mopar fluid smells and looks like a light trans hydraulic fluid, took just over a liter, ridiculously expensive. I changed the rear diff fluid to full synthetic 75W90, no moisture in it. I have only been able to suck a bit out of the front diff. I may have to go to a timy hose. While I was dropping the engine oil, I noticed a wet spot at the trans with some oil blown back. I tightened the bolt that looked wet and cleaned with brake fluid. It looked better but I noticed oil in one groove. Cleaned again and really got a rag in there. Still getting wet, watching it, actually a slow drip. I am positive the pan has a minor crack. Good thing CT has 6 liters of LV fluid in stock that meets the ZF spec. I am really happy I bought an aluminum pan a few months back for the ZF 8 speed. It sounds like they take 5.5 liters. Glad I was paying attention and thinking ahead. I will have double check my level and check the trans temp with a temp gun after filling.
Well it could have not lost much fluid. I added 3 Liters and it was coming out. I realized it was slightly lower on the back. Using a level was pretty much bang on, I fit another 1/2 Liter. I ran it through the gears on the stands twice I had to add fluid. I ended up just over 4 Liters, the 845RE must take a bit less fluid than the bigger transmissions. Warmed it up for a good few minutes, trans was in that 30 to 80C range, just barely coming out the hole. Put the plug back in and test drove, it shifted perfectly.
So I took the Challenger GT for a 4 hour one way drive for my Wife's eye treatment. It started out having averaged 18.7 mpg Imperial from driving in town. Doing 100 km/hr, it was averaging 35 mpg in on icy roads in AWD! I am super impressed with that, had to slow down to 80 km/hr due to shitty, snow and ice packed roads, it went down to 30 mpg. I am betting 40 mpg won't be out of the question this Summer. I also found out it has the slightly upgraded BR5 brakes from the RT, not the BR9 Pursuit brakes like one article claimed. Easy to measure through the Monza Winter rims.
Installed the Spectre cold air intake, pretty easy. It looks pretty good. I ordered a Chinese Hellcat lower air box and tube for cheap, it may replace the filter and heat dam. Popped out the the two cold air inlets by the headlights. Pretty gentle but still broke one of the tabs. Still waiting on the tube for the passenger side inlet. Getting cheap mud flaps to block more heat from the coolant bottle and maybe on the dam wall.
I added these after the test drive, should help even more.
Slightly more power and mileage. It sounds more aggressive. Some of the gain is no doubt removing that factory silencer tube, necks down pretty small..

I wouldn't be too surprised if the computer doesn't dial it back, it knows how much it's supposed to be making.
