Well, a 5"piece of sch. 40 pipe 10 inches long will give you a c:b ratio of .877:1, that should do fine or you could go with a piece of 4" sch. 40 that is 15 inches long and give you a ratio of .836:1 which is also good.

and if thoughs 2 sizes cost to much, 20" of 3" pipe will give u a .858 C:B ratio.
