SLP or spintech

[FormerStangFan]

I would like to use one of these two mufflers on my 11 expedition and have not seen a catback or any type of kit for either one. I will make it work either way but just wondering if anybody has experience with either of these? How do you like it if so?

i have the a spintech cat back on mine. i love it. it is a DI/SO due to the IRS. Mine was installed by spintech themselves. they are located in riverside.
here is a link to a video so you can hear what it sounds like.

i used several SLP parts on my Formula including their loudmouth catback and was very happy w/ it.

I ran lmIIs on my 02 and 10 mustang GTs and loved it. I've never heard them on a fore truck though
