6.4 Jeep SRT8 Exhaust Manifolds

You may be right about the exit, found this, presumably Jeep:



Then found this, seems to have plenty of turndown, but I'm thinking it is a different manifold:



Reading more, this is the AEV wrangler conversion kit and uses 5.7 Jeep manifolds from 09-10 Commander, of course the later 5.7 manifolds do share the same exhaust port configuration as the 6.1 and 6.4 hemi.





Maybe not the best flowing solution but might work in tight places.
