I have a brand new, never installed catted ZZP downpipe for 2000-2005 W-Body I'm selling. It's 3 inches with a 2.5 inch outlet. I decided to go with headers instead, and it's just been sitting in my garage. ZZP sells these for $215, I'm asking $160, and I'll pay shipping! E-mail me at david.n.spence.ds@gmail.com if you're interested. Thanks!
