Yes, but at least you provided some data when it came to the '11 vs. '12/'13 4-cat setup using exclusively GM parts. Had you have gone the Corsa route, I'm sure someone would say the HP increase is because Corsa uses a "better X" than GM.

Admittedly, I have not tested the X's against each other. My opinion is based on looking at the X-pipes I see on race cars.

My understanding is that 06-10 Z06 uses an H-pipe but 11-13 uses an X-pipe and 12-13 has four cats.
Also Jason Harding at Katech told me he thought backdating to an 11 midsection was a bolt on but then Justin Abbott at Zip Products told me it was not.
What we need is a photo of an 11 mid-section. Anyone have one?

add: I would think not. The extra cats are the issue b/c lengths change.

I just swapped in the X pipe center section into my 2008 Z. The difference in sound is readily apparent but my butt dyno isn't really calibrated enough to notice if there is any extra power to be had.

I have the 2008 mufflers with the muffler mod done and the fuse pulled on the exhaust valves so it's in loud mode all the time.
I prefer the sound with the x-pipe; it's way more exotic sounding and less motor boat lol. It's most apparent at the high end of the rpm band and then when shifting at wot...it almost crackles on the shift overrun which it never used to do. Sounds really nice.

I emailed Corsa about the 14331 X-Pipe and was told it would require cutting....not so. Just installed today, straight swap. I would recommend buying new donut gaskets from the dealer, it is possible to re-use the ones from your OE x-pipe but takes longer and there is the risk of damage.
Echoing some other feedback, the sound does seem to be a bit higher pitched and with less burble/pop noise (which I liked) and there does not seem to be as much heat from the center tunnel.....we'll see.
