At 90mm, 115mm and 168mm the two are priced identically; at 73mm the 45 is $299 against $239, and at 220mm it is $2,284 against $2,222.

Champion lists street elbows in 73mm x 2-1\/2 in and 90mm x 3 in only.

Undo the coupling bolts, separate the halves, move the pipe and reassemble. Inspect the gaskets and replace any that are nicked or hardened.
