I'm looking to get more turbo whistle on the exhaust side. I have the afe twintake,spd turbo adapters,res delete and stock muffler. I am seeing people delete the cats but most of the videos are for the 1st gen 3.5 and I have a 2017 2nd gen 3.5. Has anyone done the cat delete and would I get what I'm looking for if I did delete them

It can be done, I just did it with my 3.5 a few months ago. I still have my 02 sensors in by using spark plug defowlers. Lots of turbo noise now

Alright so I went ahead and deleted my cats. Turbos are so much louder at idle/cruise and I still have the stock muffler so the whistle is pretty much all you hear. When the rpms get up there it sounds like any other exhaust I have seen videos of..
