Likely the DHM one will but not out yet, maybe he can work it into your build?
I thought somebody made one.
I made my own with fewer bends and less angles, 5" SS core resonator and Borla race muffler with Vband so I can put a straight pipe on for the track, it was a lot more work than any exhaust I ever built but has to flow about as good as anything could. I have a single outlet, Vibrant oval, it had a rounded in edge I cut off to make it even better, oval for a bit of style, I really like the looks, low weight and better flow of straight 3" all the way through.
I was asked to duplicate it but just to tight a fit and lots of tweaking mounts, etc to keep from hitting anywhere.
