Anybody running AP Xcelerator mufflers?

They do make some great mufflers. They have a 3" in and out, 18" long case, muffler that first right on A bodies. X119 is the XLERATOR number. Are yours offset in and center out? i assume if it is an Abody it will be. If it is not and you truly need a center offset, offset out, I have one heck of good deal for you.
