No real difference in sound with the stock intake

I have added the afe intake and exhaust, the sounds are magical now

sorry...this is the new world of LS motors and more complicated ECM programming. It isn't 1998-2002 stuff...I modded those too. Those could adjust and respond very well to airflow mods without a tune. The LT4 needs an airflow table correction to utilize the extra flow...even the "no tune" Rotofab has questionable performance gains.

You should hear our durango hell cat with the AFE intake. I hate to say this out loud but it is almost annoying
