OEM mufflers are good to use with your headers. They flow very well and are light in weight. After market exhausts on a Z are more for what you like your exhaust to sound like.
Dude...you have a 427, that definitely doesn't sound like the LS6 by any means...lol.
I have AR headers, catless, xpipe and stock Ti with no bypass mod...my car sounds really clean. I'll shoot a gopro vid of it tomorrow and upload it. I'm NEVER gettin rid of my Ti...sounds so clean and more exotic than a typical American V8.
