    Yep. The Hemi's have 2.5 inch exhaust. Don't let people fool you in to thinking its 3" cause its not. Offset inlet center outlet.

    The outlet of the muffler is larger then 2.5" .. This is exactly why I decided against a magnaflow exhaust which is 2.5, no sense of installing a 2.5 exhaust when you will be adding restriction.. FYI MBRP exhaust is a full 3 inch system..

    Yeah maybe a hair larger but its still considered a 2.5". If he is looking to replace just the muffler he wants a 2.5 inch offset in center out (make sure you have it welded in).

    My friend has the MBRP 3 inch exhaust on his 06 5.7 liter Commander. It sounded like crap so he swapped out mufflers with a stainless steel flowmater 2 chamber muffler (Cant remember off hand which series). It's sounds amazing now.
