Long bed pro exhaust for short bed 3rd gen

I just find cheap pro exhaust for 3rd(350) brand new. anybody know how hard to fit for short bed?

 

Very easy if you have a Welder. Only difference i can see is the pipe on the inlet side of the muffler is longer on a long bed

 

I’m planning using exhaust clamps, since I don’t have access to tig welder (if the exhaust is stainless steel). But for 350 for the exhaust maybe worth to try.
