This is the downpipe ZZP makes for the LS4 and it fits all of them. It was in the bolt on parts sticky. Can't speak on it because I do not have one.

It will work with slight modification. However it necks down to 2.25" at the split which is why I didn't buy it. If you do decide to get it however I do have a brand new ZZP 3" catless down pipe for sale.

One of the hangers is in a different location I believe. The reason I didn't get it was because I wanted to use my Magnaflow mufflers which were 2.5" and the ZZP system is 2.25". If you get their catback with mufflers I don't think it would be that hard at all to install.

Thanks for finding that. I actually have my rear o2 disabled.

Sweet thanks. If I remember right isn't it the hanger just after the y?

I believe so, if you look at their catback, it doesn't split uniformally. It has one short pipe (passenger side) and one long pipe (driver's side) after the Y.
