I don't think the tips black would work. Painting the mufflers themselves though gives it a more upscale look and hides them a bit more. Might be something to consider.

 

I've done this before using high temp spray paint. My plan is to black out as much as possible. I like the hooker 3 inch dual tips, just need to find the correct rear groud effect.

 

There isn't any correct rear valance for the twin tips that I have seen anywhere, going to have to make or modify one.

 

That sunset gold v6 picture is comical.

If you're going to do it, please do it correctly.
Saleen's setup for duals is a nice attempt.
But it seems to be a little more than just a new valance to go a long with it...
