Dwayne, The other option you may be able to apply is the allowance 13 provides for offsetting from center. L = 4ab/a+b. Depending if you are able to install off center, and based on the pipe size hung you may be able to use a lower modulus number. This might help you size the trap member where you would like it to be size wise.
