Just like the thread title suggests, I couldn't stand the "sleepy" sound of the Hemi even at WOT and finally did decided to modify the exhaust.
Been lurking on the forums for quite some time now, but am by no means a newbie at this vehicle modification stuff. Below are my previous three vehicles - all with a stupid (and unhealthy) amount of money spent on performance or aesthetic modifications. I think I am officially a member of damn near every car forum out there!
Anyway, been researching feedback on the various exhaust setups out there and was waffling around between installing the Gibson or the Corsa (based on the positive feedback). Then I heard the Borla ATAK, but later confirmed that it required modification to fit the 5.7L perfectly. After being unable to decide, I called up my local exhaust place to brainstorm a custom exhaust. What we came up (sound-wise) is witnessed in the following videos.
Stock 5.7L V8 Exhaust (Mopar CAI installed)
Custom 5.7L V8 Exhaust (Mopar CAI installed)
I'm sure I'll play around with it more... but IMO, this is how a V8 should sound.
