Just want to double check that my 2012 1500 Outdoosman (single in single out) with the 4.7 has a 3in/3in muffler size, since I'm in the process of checking out with a new 18" Magnaflow

It might be 3in 2.5 out on the SIDO, but on the SISO it is 3in 3 out, at least for the Hemi.

That's for the dual exhaust hemis. 4.7 and single exhaust Hemi are 3" in 3" out

I just measured the end of my exhaust pipe and it was 3", does that mean that it is 3"/3"?

With the Outdoorsman you have the SISO which like I stated above is 3 in/ 3 out. The SIDO (stock "duals") are 3 in/2.5 out.
