I bought a 11 challenger se and it comes with duals. I'm replacing the factory mufflers and resonators with magnaflows, however. I need to know the inlet and outlet size that I need for the magnaflows.

Think I'm going with the magnaflow 16484 kit that was meant for the 09 and 10 challenger se's. But it sounds good so I'm gonna give it a try. It should bolt right up I believe. On youtube, charger 16936 has basically the same setup. Sounds pretty good!

How did you guys make out with this?
I also have a 2011 SE with stock true duals and would like a little extra growl.
What about just replacing the mufflers?

I am actually having dual flowmasters installed tomorrow morning. I am making a little video with the sound changes and ect. What were doing is cutting the resonators out, which is right after the x wield. Where the resonators were is where the mufflers are going. From the Mufflers, fresh pipe is being laid and will be saving the tips.

I am the first in my city to get this done (only a few shops around) so they're not sure what the results will be but they are excited. Cant wait to hear what this pentastar sounds like!

I may be wrong but i thought the resonators where under the trunk and the mufflers are after the x pipe.
