I'm wondering if a catted H-pipe from the 2012-2013 Z06 will match up to the older manifolds and front cats from the 2006-2010 Z06 cars?

No it won't unfortunately -

You will have to have the the down pipes from the 2012-2013 as well - the manifolds off the motor are the same but the down pipes and X-Pipe are set-up totally different -

I actually did some research myself and found out exactly what you said.

Thanks brother

Right on - I have the 2012-2013 set on my 2009 LS3 A6 made a huge difference right off the bat

Thanks,Matt

I'm gonna have to ditch my AR long tubes and go back to stock so GM can do the emissions recall. Can't smog or register without this.

After that I'm gonna install the older LS7 manifolds, cats and H-pipe, which I bought years ago.
Oh, also have to save my A&A tune which I'll install after the Z06 parts go in.

Bummer that you have to ditch your LT'so

You will need to get a retune after the LS7 exhaust install. It will be necessary to rescale the tables and trims

On my C5 (F/I) I removed my Kooks setup and went to the LS7 set into 3" B&B Fusion my after dyno was 734.2 RWHP down only .4 RWHP (734.6 RWHP with LT's)

But the initial run was down a lot, took some tweaking and tuning on the dyno to get all the tables and once they were, the results were clearly seen.

I'm gonna save my existing A&A tune and reinstall once the LS7 parts are on the car.
I talked with Andy and he said his LT tune should work fine with the Z06 exhaust.

Sounds good -

But some day have it ran on a Dyno just to check it out, it will be worth your while!

Thanks,Matt
