I have a 2012 Ram 1500 ST rcsb with the 3.7 V6. I am looking to upgrade my exhaust. Not willing to pay for an off the shelf kit, so I will be building it myself with help from a friend. I would like to change the crappy factory y-pipe with the magnaflow version and switch from the anemic sounding muffler. I need to know the following:
1) Cat to y to muffler pipe dimension
2) Muffler input dimension
3) Muffler output dimension
I searched the forums and cannot find a definitive answer to any of the questions for the 3.7 V6. Thanks for any help!
