I had a post last week (too lazy to search for it) asking which one to keep, and flirted with dyno comparing the two. But once i had both of them in my possesion it became obvious that would be pointless. The have got to be made by the same people. same welds, flanges, bends, ports, everything. identical. The only difference is the o2 Bung placement. i took some pics (old camera)

I decided to install the holley header, so that means i have an brand new dcsports header (only opened to compare) that will be going for sell.

 

well feel free to sell me that un-needed header for 150 bucks

 

sorry can't take a hit on it.

350 shipped.
