First I want to say that the car sounds amazing, its just too damn loud. It wasn't that bad until I did the heads and cam. Now it twice as loud as my 69 big block vette. Not a good thing in CA.
What are most people using? Are they adding a muffler or simply replacing the GMMG resonators? If so what mufflers look and sound good.

I wouldn't hack the GMMG.. you could get some good money for it if you decide to sell it eventually. I'd add a resonator to the Y section of piping before anything. I know Kooks has some small resonators, but I can never find them..
