Im not sure if something like this would look good on a Diablo run as a single:

That is the same muffler that I am going to use although I am headed for the GTR look with the muffler mounted on an upward angle.  I'm going to have to cut off the tips and rotate them 180ΒΊ.  I don't like the third option.  My $0.02  Jim

Im almost ready to swap out my sbc/5 speed with my LS4/4t65ehd. The sbc is still in my Diablo and Im still going to be driving it until I have everything completly ready to swap. I figuring it will take only take me 2 days to do the swap. Im just waiting for my Microsquirt to come back from getting another board put in, I had a little accident with it. Other than that everything is ready, I got my trans controller installed with paddle shifters, the LS4 is done, axles are done, and have everything ready except exhaust.

I still have the factory exhaust manifolds on the LS4, with the factory crossover pipe that feeds into the rear exhaust manifold. So from here Im not sure what I want to do, should I "Y" off the rear manifold and run 2 seperate mufflers or run into a single in / dual out muffler? And the big question- would a Diablo Roadster look wierd with 2 exhaust tips coming out together or should I stay with the factory Diablo look with 2 dual out tips seperated?

Please forgive my super quick photoshop diagram, but hopefully you will understand what Im asking:
