Factory exhaust length?

[hemisport5.7]

Hey guys I was wondering if some of you could chime in with some insite on factory exhaust system lengths? Currently I have a 2015 ram sport regular cab with the 6 4” box and I want to do the mufflex delete kit. Unfortunately when I bought it the previous owner had a Flowmaster welded in solid. Well I came across a set of tailpipes for free (with the resos still in) from a 2017 crew sport. I was wondering if the lengths would be the same. I have not crawled under the truck to see if they would work. Any help would be great.

The tailpipes after the muffler are all the same length,it's before the muffler where the lengths are differant
