As far as I know no one makes it. I was looking for a while and even emailed MBRP and they said there is not enough room. I am sure with a big enough lift you could make something work but over the rear axle and around the spare tire is already pretty tight with the 4" cool duals.
Not exactly what your looking for, but I am pretty happy with my magnaflow 5" stainless single. Fit n finish is great and one of the only places I could find 5" in stainless, even comes with a cat delete pipe in the kit (nice little bonus)
