    This is the only thing I wish there were more of on the Hellcat. I really like the exhaust note but I really miss the crackle when you lift off the accelerator or rev the engine.
    There is absolutely NONE.
    Seems like I used to hear a little until the first TSB and computer flash last year. Now...nothin!

    Really? I used to get it on Dante, and now I get it on Jimi. That is odd.

    That is surprising, I get it nearly everytime I let the engine brake the car.

    Sometimes I get the crackle but not all the time. I took the Cat to a classic car show last weekend. There was a disabled chap eyeing the Cat and we got talking. Shall I fire it up. Blipped the throttle and it crackled like a good un. His face lit up. I think I made his day.

    If you want more and some additional volume, do a muffler delete but be sure to leave the resonators on.

    Get a lot of crackle in all modes, but especially when the A8 downshifts.

    The engine break crackle is loudest when the engine is cold, I guess because the breaking is more effective?

    Can someone explain the physics ?

    Don't know that this is true but my thinking is, the motor is probably running a little rich with fuel when cold. More and louder pops in the exhaust.
