on my 06 2500 hemi, I want to run identical tail pipes as the srt10 ram, stright out the left rear.

im not sure on the oem tail pipe size or if srt 10 ram mufflers are behind the rear diff.

ex pipe size, the rest of my system will be 2.5 in x2. from the cats back.

 

Muffler is in front of the differential, same location as your 06 Hemi. I cannot tell you the size of stock pipes anymore, been to long. Oh and the pipes come out the right side

 

The pipe is 2.5. Stock there is only one muffler, two in & two out. Don't use the stock muffler.
