reducer question

where can i buy a reducer or adapter to go from 2-1/2 to 3-3/4inch and another reducer or adapter to go from 3-3/4 to 5 inch.
here's what i've got. a '92 ford f-250 with a 7.3l na diesel. i'm wanting to install some 5 inch stacks true dual.
my plan is to cut the exhaust off as it comes down the back of the engine.
there i will install a 2-1/5 inch to 3-3/4 adapter.
from that i will run 3-3/4 inch flex pipe to the outside of the frame at the front of the bed and install a 3-3/4 90 degree elbow to to 3-3/4 to 5 inch addapter into a pre-made flange, or mounting assembly (haven't got that far in the design stage yet) that will exit thru the floor of the bed where i will install the stack.
i will do this on both sides.

Where do you plan to get 3 3/4" flex pipe?

Also, are you sure about running the pipe UNDER the frame, it'll be very visible there and prone to damage.

Kinda sounds like you're doing it the hard way.
