WV, is that as in
West by golly Virginia? Must be since I see Ravenswood as your location. Been through there many times. My brother lives "up the river" just east of Moundsville near the border with PA.
Having removed and installed the pipes on my car twice, I know what you're up against. As d_ford says, work them back and forth. But on installation, clean the slip joints with with a wire wheel or brush and coat them anti-seize to help rust-proof the mild steel. This will ensure the job will be a little easier the next time.
