Default Do stock C6Z06 headers Fit a C5?

Hi guys,

need your help here, has anyone installed stock C6 Z06 headers and midpipe on a C5? Does it fit? I searched and could not find anything.

I have a friend with a C5 Z06 and he wants to buy my setup but I am not sure if it would fit. Thanks in advance for the help

Yes they fit with very minor modifications.
Search again, because there are at least 2-3 threads with detailed information about it.

The LS7 exhaust manifolds will bolt onto LS1 cylinder heads. I don't know if they will interfere with anything in the C5. But they will certainly need custom pipes to meet up with the C5 exhaust. It will not be a bolt-in swap.

Stock C5 manifolds:

Thanks Alex, I searched again and found both Threads. The keyword was manifolds. Thanks again!

Thanks for the reply I saw on the other threads that they fit just fine.

If you found the thread then you also seen my posts and pictures along with others too!

I have done this already and am waiting for my B&B Fusion (Bi-Mode) 3" all the way the axle!

If your friend is going to do this there is NO need for him to drop down to 2 1/2" mufflers - he can continue the 3" all the way over and be fully slip fit like the Z06 etc.

If he has questions you can have him call me about this set-up too and fitment etc. 661-406-7516

Thanks,Matt

Dyno Update - results are in - 4/19/2013 - Big thumbs up to Charlie and Austin @ RPM Motors

First it was necessary for me to install a "PROPER" Crank Case Evacuation System - here is my write up on my Monster 2 Catch Can Installation with Pics -
Thanks to the proper guidance of Charlie I got headed in the correct direction and was able to get the proper set-up for my combo, I wasn't able to go any further a few weeks back specifically because of an INADEQUATE Crank Case Evac system

Dyno Results: I lost - .4 RWHP and 15 RWTQ - "NEW DYNO SHEET"



"OLD DYNO SHEET" -




Thanks,matt
