2012 6.4L Corsa Xtreme Exhaust Clip. Charger, 300, Jeep SRT8. Currently, any aftermarket exhaust for the 392's are going to throw a P0471 code due to a reduction in back pressure (no pressure flaps inline like on the stock exhaust). Corsa is working with Mopar to release a flash update to do away with the back pressure check so a free flow exhaust can be used (it's in Mopar's interest also).
The new exhaust from Corsa can come in either the standard stainless tips or their new "Black Diamond" stainless tips.
