I think the only way to figure it out is by having both of them and actually doing a side by side comparison and making measurements. The two chassis might be different and I don't think a simple extension adapter will make a coupe exhaust fit the sedan. Hopefully two members who live close to each other, one with a sedan and one with coupe, can compare both stock exhausts (if they have the stock exhausts uninstalled). Or just the mid pipes since the axle backs are pretty much the same.

Surely you could take it to a muffler shop to have it altered. I'm sure it's just a matter of the mid pipe being longer

I'm sure it is. The old DC and EG chassis was the same thing. You wanted the coupe cat back to fit your sedan you needed to add a couple of inches to the mid pipe. I don't see why it wouldn't work with this setup

Actually seeing how INJEN has an axle back for both the coupe and sedan, makes it seem that the difference is in the mid pipe only.
