I only used the single AWI supplied, but would recommend two muffs from the start for better heat. Maybe you could get them to add the transfer studs to a second pipe. I have the IO360M1B 180hp, and since a second muff is not fitted can not make a location recommendation.
How hard is it to attach heat muffs? Ideally for MN winter I would like to have two muffs.
I have two muffs which attached very easily, they are configured in series with one position having the welded studs. With two muffs you will have plenty of heat as long as you minimize the airflow thru the known spots.

I just bought an RV-7 with a Sky Dynamics 4-into-1 exhaust and their cold air intake.
I realize the OP is inquiring about RV-9 installations and I don't have much to offer with regard to the installation but the Sky Dynamics 4-1 definitely sounds very nice!
I sent an inquiry to Sky Dynamics for my RV-9. Thanks for the pointer.

Would you mind sharing how you secured the cable loops?
Done looks like they gave a crushed tube on the end, like a swage. The stock AWI I received simply recommended to use a center punch and stake the holder from the outside.

I had to shorten the loops a bit for proper clearance, after adjustment, crimped on a short piece of Alum tube on the end of the cable.
Used a standard terminal crimper to make the crimp.
Correction, I used Stainless tube.
