Gotta question for yall.

Maybe someone can point me in the right direction.

I purchased a 5" TBE from FLO~PRO model number 1648.

My truck is a 2012 RAM 2500 Mega Cab.

So my question is the stock downpipe has a 4" flange correct?

The 5" downpipe I purchased has a 5" flange.

Will it still mate up to the turbo being an inch bigger?

Do I need to upgrade anything or should it be plug and play?

I would hate to take everything apart to find out the downpipe doesn't match up to the turbo or is too big any help would be appreciated.

I have seen videos on YouTube on installation and it looks like everyone that is installing the 5" downpipe matches up but idk.
