Here are some pics of the exhaust on my car. It has PaceSetter headers, a 3" pipe to a highflow cat, then a 3" Magnaflow muffler as a resonator. From there, a 3" pipe connects to a 2 1/2 " Y " pipe, and back to 2 Dynomax Super Turbo mufflers.

Pardon the picture quality, I took these using my phone...
