Leadfoot99Z28

I have a 2 chamber flowmaster on my 99 Z28, and my girlfriend is getting jealous because she says her 84 Z28 isn't as loud with her 3 chamber flowmaster... i think we are wanting to install the dynomax bullet for her so she'll be satisfied, but i am curious as to how it would be installed seeing as how she is running a cross flow muffler now, and the dynomax is a single in and single out muffler...err "resonator"...whatever...
anywho, i'm totally ignorant when it comes to exhaust, so can anyone help me with some ideas, or if you have pics of the dynomax bullet on your car or a similar setup i would be obliged...thnx
