This is the factory titanium exhaust used on the C5 Z06's. It was mildly modded with strategically placed drill holes (4 each pipe) giving it a more aggressive idle and rev. It was on my near stock '99 Hard Top C5 (also called Fixed Roof Coupe); I have since upgraded to a Corsa Pace system with tiger shark tips.
You drilled holes in your exhaust? LOL!!!
