Trying to visualize what this means is giving me a headache. ( and sometimes - fits of laughter )
Can you fab a composite duct to meet your requirement a' la Dan Horton style?
Can you just put a 45* fitting on the oil cooler air inlet, this will push the scat off to the right, and clear the muffler better??
Or, even a less than 45*------whatever will do the job.
Wouldn't the SCAT tubing withstand more heat than fiberglass?

I had a similar situation on a heat muff scat tube.
What I did was bend the scat to the position you want it and temporarily hold it there with tape or wire or whatever works. Then, using some red RTV, apply a sizeable "glob" in the inside corner of the bend. Smooth & blend it accordingly. Once the RTV cures, remove the tape or wire and it will keep its shape. Since you said you wanted an offset, you may have to do one bend at a time. Also, you could even do this on the work table if you know what your geometry is.
