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".
