Finally got my SLP runners I ordered back in December, but I am not the 1st too receive them. So now I gotta ask why where they returned? Their overall quality is pretty crappy, but nothing I can see that would make them not work. Still the fact it took so long, was a production problem delay and when I asked SLP they didn't tell me what the problem was.

The flanges look straight with ruff straight edge. One looks like it was poorly surfaced with a ruff file on the plenum and base ends. And the ports all look like someone started too port them or clean them up a tad on both.

Maybe this is the norm for SLP?

 

After looking at them some more they got a spot that is sticky from what I assume is duck tape and they smell like they have been used. few scraps and couple grease spots. Plus one spot of the flange that is dented(red circle) and may not seal well.

 

Just an update the vendor got me a new set of SLP runners.
