Man the quality of the fabrication on these EOS pipes is terrible, I’m definitely not putting these in.
These maybe ok on a street car that doesn’t get pushed to much but these welds will let go quickly on a car that sees any track time…

​​​​​​What exactly are you seeing that is a visible quality issue with the welds? I didn't get mine x-rayed but from a visual inspection I saw no cracking or flawed connection points.

Almost no penetration of the welds, no inner weld on the inside edge to the flange, 1/16 gap from the straight to the angled tube and the weld didn’t even fill or penetrate the gap…
Its just crap.
But it’s on me for expecting quality at $400 shipped for both pipes….

I will keep this thread updated if they crack or self destruct under street conditions. I wouldn't expect someone planning to track their car to go for a $350 pair of downpipes when quality headers are around $2000 though.

Touché,
I don’t want to do heaters, not so much the cost but the heat associated with headers.

Has anyone tried the Alpha Speed pipes?
Pictures look much better made, even show welds on the inside and not that much more $$&.
