Go with the Mopar one. Looks killer!
But if you have a 5.7 R/T don't order one from Dodge. They are still confused which one to use.
They'll try and sell you the one for the 6.1
Just buy a 5.7 one for a Charger off ebay instead, but you need to pick up a small 40 cent hose clamp to finish the job totally.
