Dif between QC/RC and 04/05 vs 06 exhaust?

[SRT-11]

so I figure the headers are the same on all models, but what about the midpipes and cat back? are the midpipes the same and the cat back lengthier? cat back the same and midpipes lengthier? Thanks guys!!

never mind, they're all the same, the midpipes are different.

'06 cat back hangers are different since the frame is a 3500 - '04 and '05 cat backs will not fit '06's without hanger relocations -- as far as I know, only Mopar/Borla makes true bolt on cat backs for '06's - that was the case when I put mine on a few months ago -things may have changed by now - fwiw.
