A little bit off topic. But could Zeta (G8, Commodore, Camaro) headers fit with out further modification? If so, any part numbers?

I still say the stainless works are worth it at this point... BUT...I really wish someone would step up and make a steel or coated header for half the price. I already have the SWs...but it would still be nice for someone looking to keep a tighter budget.

To answer your question....Everyone seems to have their own experiences on what will fit with "X" amount of modification etc etc. But its not all put together with conclusive info.

I know there are some guys over on thirdgen.org that have done it...and they havent posted how or shown pics... I wish someoen would.

All I know is...I built my own y-pipe to go with my custom crossmember and that was a bit of a pain. The idea of cutting headers and having to mod primaries scares the crap out of me. haha.

Agreed. A coated set for half the price would be great for us budget guys.

For those with a little bit of fabrication skills, you could always make your own. That's what I did. They turned out pretty good (especially since it was my first try at this). I should have gotten them coated, but when I finish welded everything, the primaries moved a little so I didn't bother. I'll make another set when my car is done.

Not too bad considering all I had to work with was a cut-off wheel and a grinder.
