So I purchased a flow master super 10 for my 21 bighorn - muffler shop says it won’t work/fit with this truck- I’ve saw videos with 2020 rams with it- did something change?

did you purchase just the muffler? if so, they will have to unclamp your current OEM muffler, and then weld some new pipe in to install your flowmaster. They either don't have the tools to be able to do this (requires specific measurements, bending machines, etc), or the inlet/outlet measurements on your muffler are so far off from what your OEM exhaust system is that they can't work with it. doubt thats the case tho

Yeah when I was telling the guy I wanted to replace the current muffler with the FM and delete the back resonators - dude was trying to push just chopping the muffler and that be it - I’m betting he didn’t have the right machines to bend pipe right or just didn’t want to put that much work in it - he ended up chopping the muffler for $50 so until I find someone else to check it out I’m rocking that set up

hahah i ran a muffler delete when i first got my truck before my actual exhaust system came and it was LOUD. yeah sounds like they just didnt want to deal with doing that then... takes a lot of time doing custom work like that. good luck with it!
