Hey everyone, I'm new to this forum but I've had my 2021 charger scat pack for 4 months now and I've done the mid-muffler delete, the exhaust was loud and popping and burbling on all decelerations in pretty much any rev range. Now the popping and burbling is almost non-existent, I've spoken to a few people and they think it's a correction table that is compensating for the increased airflow from the mid-muffler delete. So my question is how can I tune more pops and burbling into the engine.
Thanks guys!

So unless the mid mufflers are different from the Hellcat's, they should be straight through. They just have baffling around the inside for about an inch or so.

Since there aren't any sensors back there, I can't see what would change anything. Did you mess with the active exhaust valves?

@baabootoo
I have not done anything with the active exhaust valves.

In all modes? I thought that it had to be in SPORT or TRACK to make those sounds.

It does a little popping in track mode but I don't like to daily drive in track mode. It used to pop and burble no matter what mode I was in especially after I did the mid-muffler delete.

I always left my transmission in track mode. Why don't you like it?

I have heard that it is hard on the transmission to leave it in track mode all the time. Any problems?

SPORT or DEFAULT?

 

[Johnson392]

right after i had the mids cut out it popped and sounded great in default or auto mode and it sounded even better and popped louder in sport and track, now... it doesnt do much .

Not a one.

I don't understand why people like that noise.
