Adjusting the GMMG is not simple but if you know what you're doing it doesn't rake long to get them right. Your shop may not have anything wrong but they didn't do too much right! Take it to another shop.

UHHH....if you're talking about the PONTIAC, it's vinyl from Fourth Circle Designs. If you're asking about the bottom, it's painted.

A friend of mine had GMMG on his with manifolds and cats. It was extremely quiet. I never cared much for the set up. I think it looks like poo and is overpriced.
