LARGEST mufflers that will reasonably fit under a Fox coupe?

What are the LARGEST mufflers that will reasonably fit under a Fox coupe?

I have a 1993 Mustang coupe with a dohc 5.0 out of a 2011 GT. It is loud and I want to make it very quiet. I've decided on 3" Magnaflow mufflers and I'm wondering what are the largest Magnaflows that will reasonably fit under the car with my non-cat 3" Bassani X pipe and stock location 3" tail pipes.

Here are the options:
3" inlet and outlet Mangaflow mufflers

MagnaFlow 14239 5"x8" - 14' long case - 20" long overall

MagnaFlow 14264 5"x8" - 18' long case - 24" long overall

MagnaFlow 14578 5"x11" - 22' long case - 28" long overall

MagnaFlow 14261 5"x11" - 24' long case - 30" long overall

Will all of these fit? If not which ones?

Thanks!
