Tomei's new stock replacement header looks promising I think. I saw it over in the other tomei install thread. Its the same general design as the stocker but tubular.

I think this should be just as good as a ported stocker if not better in the mid range area. Gotta find out how much it is though.

 

keep the BR ported stocker or go with the Shearer Fab one that 9sec9 said about...the testing that was done showed very positive results!

 

Thanks for the input everybody, it's useful info!

 

It's in the midst of getting coated now.

Several more manufacturers are now producing replacement manifold these days as well.

Here's some results from ours...

Not quite $1200. If you want anything that's going to hold up to the test of time spending the money once and only is the only way to go.
