Just fyi, I too have a set of cx racing headers I was going to use. Then I realized that they are only 1 5/8" primary's. The guy over at ls1rx8 says he is working on a set of full lengths with 1 7/8" primarys that will also work with auto trannys.

Now I just have to find someone to buy my cxracing headers lol.

I just finished reading this for a second time. Why add the 470 ohm resistor on alternator wire?

I'm super pumped..they look fantastic, and fit like a dream!















I couldn't be more pleased with the headers...which also means the old set of shorties I had, that were never used are for sale! PM me if interested.












Also I have 2 sets of the stock C5 engine mounts that I no longer need...





Hopefully this week/weekend I will be able to get the fuel system straightened out, and all mounted, as well as a few other lingering items!

I used a set from CX racing. The drivers side didn’t fit perfect, and I ended up having to ever so slightly notch/grind down an ~1/8 of an inch at most of material from the drivers side motor mount (technically the pedestal the mount bolts too) to get it to fit where I was comfortable it wasn’t going to touch as it naturally expands when hot, or from the vibration ect. For the price though I love them, and glad I picked up a set.
