I ran across this on eBay and it is listed as a replacement rear exhaust manifold for a Bonneville 1997-2002. It looks like a stainless powerlog made for the rear. The price looks attractive, so I wonder if this would be a lighter better flowing alternative to a ported stock cast iron manifold?

That's $135 towards headers.

I've already got the front powerlog so I wont be going the header route...or either I'll just wait and do rear powerlog if I go turbo.

Our rear mnfld is'nt cast it's stainless(409)this mnfld will bolt up but will not line up with a GP DP ,if you want a ported rear just send me a stock mnfld. and I'll fix you up.Chico(pops)

I have a Hulkspeed Rear PEM I'm trying to get rid of. Rick has first dibs but if he chooses to pass them I will let you know if your interested.

Also I wonder since all the applications are on the full size cars would there even be room in front of the firewall for it.

I understand from all others that the PEM wouldnt net my car much improvement, and I'm not looking to go wild with performance.

I'll pass on the PEM. Thank you.
