Installing Muffler 2.5 & 2.38 Pipe

Does anyone have done installing a flowmaster muffler super 44 on tacoma 2016? I have Muffler 2.50 OD and want to connect it to tacoma exhaust pipe 2.38 OD. I have a problem installing them with clamp.
Most clamp size are
2.50 x 2.25, 3” x 2.50, And butt clamp.
I don’t know which one is.. can anyone help me.

 

I am running that muffler. You should just weld two connector flange (tapering) pipe pieces from the stock piping to the muffler. A shop could do it for $75

 

Did you figure out a solution? I am contemplating doing the same thing.
